Sasken - BANGALORE July 26, 2012
INTERVIEW EXPERIENCE:
Hi. I was one of the 12 people who were selected in the sasken campus drive at Sir MVIT Bangalore. I'm from computer science branch.
The interview process consisted of three rounds:
1) Online aptitude test
2) Technical Interview
3) HR Interview
1)Online aptitude test:
It consisted of four sections with 25 questions in each section. First three sections were Quant, Verbal And Logical Reasoning. Absolutely no preparation required for these sections. All questions were related to basic maths. But going through RS AGARWAL book will help. The fourth section was MCQs on 'programming'. nothing related to any specific programming language. Here your logical thinking abilities w.r.t programming are tested. If you are strong with basic concepts of any programming language then this section can be cleared easily. Although 'Test your C skills' book by Yeshwant Kanetkar helps.
Out of the 127 students who wrote the test only 27 cleared. Max filtering is done in the first round itself.
2) Technical Interview:
HIM: temme somethin bout yarself
ME: ...
HIM: what are your goals??
ME: ...
HIM: which is the subject you are strong at??
ME: C programming.
HIM: tell me any subject other than programming
ME: OS
Then he started asking questions about OS. Some of the Qs were like this:
>different types of OS architectures. . . (i had no idea! :P)
>What did u learn i OS
>tell me about processes
>about threads
>difference between processes and threads
>RISC and CISC (i said i donno)
Then he asked me to rate myself out of 5 in c and c++.
(if you tell 5 then they will screw the shit out of you!!. play safe)
Then he started asking some more Qs like:
>allocate memory for 2D array using malloc
>prog to reverse a number
>program to reverse a link list
>program to find if the link list is circular
>notations for finding efficiency of an algorithm (big oh, omega, theta)
Out of the 27 people only 12 cleared Technical round.
3) HR Inteview:
HIM: temme somethin bout yarself
ME: ...
HIM: what are your goals??
ME: ...
HIM: Y sasken?
ME: ... (listen to the ppt and tell stuffs from that)
HIM: y shud i hire you?
ME: ...
And some more commonly asked HR round questions.
HR round was just a formality. All those who cleared Technical round cleared HR round also. Finally results were announced and Welcome letters were given.
The process started at 9AM and got over at 10PM.
Its more than enough if you start preparing 3 days prior to the placement process.
Go through the basics from all the subjects from 3rd semester. and prepare for any one subject thoroughly since questions, in interview, will be asked on 'your' area of interest.
ALL THE BEST.

Sasken Communication Technology ltd - Pune, Feb 29,2012
Hi Friends
I am Ankur Bansal, I have done PG-Diploma in DIVESD from C-DAC ACTS, Pune in AUG-2011 batch after B.Tecg in Electronics & Communication. . I was selected in SASKEN during the campusing at C-DAC ACTS Pune held on 29th & 30th Feburary 2012. Here, I have tried my best to help you guys by giving information about the pattern used by SASKEN. There was no negative marking but there was individual cut-off marks for each section (in written round)
GENERAL PATTERN
1. Written test
2. Technical interview
3. HR interview
4. Personal Interview (just as a formality, in this part of interview they will ask, whether you agree with the bond or not and finally they will give you an offer letter).
1st round is totally based on online C programming test which contain 3 parts: beginner, intermediate and expertise. Question level increases as you move to beginner to intermediate to expertise.
Maximum question is based on file handling. This round is tough. If you clear this round then its easy for next round.
In Technical Round, as I was from ECE department and did Embedded course. they asked me most of the questions from embedded side and linux device driver and C & DS.
the questions were like
1) what is your aim in life?
2) what is difference between static and volatile class?
3) what is difference between structure and union & enum?
4) How dynamically memory is assigned in C.
5) some program based on linked list and stack.
6) what is difference between process, thread and task?
7) what is page fault?
8) what is semaphore, shared memory. Difference between semaphore and mutex?
9) What is the specific use of union in C i.e particular application of union ?
10) What is AVL & Binary Tree ?
11) How to see, total memory consumed by our C program ?
12) how to Play song and open web browser from C program ?
Around 45 min, interviewr asked such question and I answerd very clearly. After these basic
question interviewer asked me about my project for about 50 min.
In HR round they asked me the basic questions. So, just prepare some hr questions which are generally asked during the interview.
and remember one more thing, collect some information about Sasken (visit the website of sasken you can easily gather some information).
So, friends what I feel, once you clear the written round, there is a maximum chance to get selected because the rest of the rounds are not so tough. prepare the C, C++ part well. Finally I want to wish you all "BEST OF LUCK".

SASKEN PAPER & INTERVIEW - 15 OCT 2008
Hi Friends
I am Anuj Sethi, recently I got placed in SASKEN COMMUNICATION TECHNOLOGIES on 15th Oct. by God's grace..
A total of about 600-800 students appeared in the campus selection, out of which 66 cleared written then near about half of them were eliminated in Tech. interview and finally about half of them were eliminated in HR.
The selection process was divided into 3 parts:
1. Written Test (65 Questions in about 75 mins.)
2. Tech Interview
3. HR Interview
Written Test:
It was further divided into 3 categories (No sectional cut-off and no -ve marking):
1. English / Comprehensive part (15 Questions): This part includes synonyms, comprehensive passages etc. This part was not at all difficult and no preparation for this part is required according to me.
2. Verbal / Analytical abilities (25 Questions): This part was also easy and Verbal & Non-Verbal Reasoning by R.S. Aggarwal is enough to practice this part(however non verbal part is not required for SASKEN). It includes Syllogism/Logical Reasoning, coding-decoding, Puzzle test (a bit difficult) etc. I dun remember exact questions but m giving some similar examples.
(i) 3-4 questions were from Logic section from R.S. Aggarwal for ex:
(a) Some books are pens.
(b) Some pens are erasers and some options were given...
ans: none (coz both the statements were starting with "some")
(not exactly this question was there, but ya 2 of them were alike, as both the statements in them, were startin with "some")
(ii) about 5 questions were based on statement-conclusion. for ex:
Statement: All athletes do not drink.
(a) Mohan is a athlete.
(b) Mohan is not a athlete.
(c) Mohan drinks.
(d) Mohan do not drink.
options: (1) a&c (2) b&c (3) a&d (4) b&d
ans: (3) a&d
(III) 1 condition on Puzzle test (Family Based problem, type-6 puzzle test under R.S. Aggarwal) was given and 4-5 questions were based on it. it was a bit confusing and difficult, so practice these problems well else if you find it time consuming and still not sure about the result then skip this problem.
it was something like this: there are some family member: P,Q,R,S,T,U..
-->P and Q are either males or females.
-->R or S or both are males
-->T or U or both are females
(Q1) who is the son of S
(Q2) who is wife of P
(Q3) how many females are there etc...
(iv) 5-10 questions were based on coding-decoding. these were not too difficult to solve but practicing these will save your time.
3. Programming / C ability (25 Questions): This was most difficult part and you need to practice a lot for it specially on loops and on pointers other wise u can't do it.
Some of questions I remember were something like this:
(i) if there is a character pointer say *p having address 100, if we do p++ then what address will it contains
(a) 102 (b) 104 (c) 108 (d) 101
ans: 102
(ii) for given pattern what will b the correct algo:
11
12 22
13 23 33
14 24 34 44
some thing like this... and some algorithms were given and u have to choose the correct 1.
(iii) 4-5 questions were based on loop problems. A code was given based on loops (quite complex) and u have to choose the right output of it which was quite hard to derive.
Technical Interview:
(Experience and Questions asked)
All the interviewers were quite good so don't get nervous about the interview... just be confident and don't bluff at all if you don't know anything, rather try to divert interviewer's attention on the points/language/skills or subjects in which you are good, but do take care that in that thing you must be sound because after that they will ask each and everything about that particular subject. Like I said that my programming skills are good then he given me 2 programs to write and asked a lot about C++.
Firstly he asked about me and then about my aim... and to explain that...
C programs asked:
1. prog. to display prime no.s
2. prog. to display even no.s.
About C++ he asked me:
3. virtual pointers
4. runtime polymorphism with examples
5. to inherit 3 classes from a single base class in public, protected and private mode and also what is the scope and how data members and member functions of base class will b derived, used and their scope in inherited classes.
Also he asked me that what I meant or understand by telecom, I asked in what sense... he replied: like networks, what u understand by network or what telecompanies do...???
Also they can ask you about your projects in detail and other questions asked from my friends were:
1. to draw block diagram of microprocessor.
2. program to swap using function call by reference and value.
3. difference b/w structures and unions.
4. static and dynamic m/m allocation.
5. task scheduling.
6. multiple inheritance.
HR Interview:
Interviewer was a lady and she was very polite...the interview goes as following:
Lady: Tell something about yourself.
Me: ...bla...bla...
Lady: Tell about your family background
Me: ...bla...bla...
Lady: You have mentioned "adaptive" in your strengths...what do you mean by it and explain in what sense you are adaptive..?
Me: ...bla...bla...
Lady: support your answer with a live example...
Me: ...bla...bla...
Lady: any other instance or example that shows you r adaptive...
Me: ...bla...bla...
Lady: r u ok with the bond?
Me: ya, no problem...
-----then she signed the offer letter and handed to me----
Lady: congratulations Anuj!
Me: So am I selected mam?
Lady: yes!
Me: Thank you mam! thank you very much!!!
Me: Can i ask u one question mam?
Lady: Yes...
Me: Any negative point in me?
Lady: you should work a lil bit on your communication...
Me: k...thank you mam!
Me: Nice meeting you mam!!!
***For SASKEN you need to be good in Data Structures, Pointers, Computer N/W and programming skills.
***GuYs never underestimate yourself... I've done this after facing about 5-6 companies b4...
Always remember when God ordain luck for you... no-body can stop you!!!
Never loose your heart if u dun succeed rather try n try again until u succeed...

SASKEN PATTERN & INTERVIEW - 23 SEP 2008 - KOLKATA
Hi Friends
I am Ratnesh Kumar Jha from Murshidabad College of Engineering & Technology. I was selected in SASKEN during the pool campusing at TECHNO INDIA college (Kolkata) held on 23rd & 24th September. Here, I have tried my best to help you guys by giving information about the pattern used by SASKEN. There was no negative marking but there was individual cut-off marks for each section (in written round)
GENERAL PATTERN
1. Written test
2. Technical interview
3. HR interview
4. Personal Interview (just as a formality, in this part of interview they will ask, whether you agree with the bond or not and finally they will give you an offer letter).
Written test comprises of 65 questions having three different sections
1) English 2) Verbal & non-verbal reasoning 3) C & C++ questions
There were two paragraphs (5*2=10 marks) and Synonyms (5 marks).
IN reasoning part, there were 2 puzzles (5*2=10 marks) and the other questions were
from coding & decoding (5*1=5 marks) and logical reasoning (syllogism). i don't remember the rest.
In the C & C++ part, most of the questions were from pointers, functions, files, array, dynamic memory allocation (malloc based questions). the pattern of the question was to find out only errors or the o/p of the given program.
In Technical Round, as I was from ECE department they asked me most of the questions from my core subjects.
the questions were like
1) what is your aim in life?
2) which is your fav. subject? (I said microprocessors and networking)
3) what is the diff. bet. 8085 and 8086?
4) what are the no. of flags in 8085 & 8086?
5) details of flags.
6) why 8085 is called 8-bit processor and why 8086 is called 16-bit?
7) about address bus and data buss.
8) what is the difference between software and hardware interrupts?
9) what are the different layers in osi model?
10) difference between internet model and osi model ?
11) what is TCP and which layer it belongs to?
12) what is UDP and which layer it belongs to?
13) diff. between tcp and udp?
14) what is crossbar switching and strowger switching system?
15) diff. betwwen analog communication and digital communication?
16) what is the difference between structure and pointer?
17) how to create a structure?
18) what are the storage classes? explain register and static storage class?
19) write a program to swap the values using pointer?
20) how the memory is allocated in case of structure and union?
For the ECE students most of the technical questions were asked from microprocessor, networking, digital eloctronics, basic electronics and few questions were asked from C, C++.
In HR round they asked me the basic questions. So, just prepare some hr questions which are generally asked during the interview.
and remember one more thing, collect some information about Sasken (visit the website of sasken you can easily gather some information).
So, frnds what I feel, once you clear the written round, there is a maximum chance to get selected bcoz the rest of the rounds are not so tough. prepare the C, C++ part well. Finally I want to wish you all "BEST OF LUCK".

SASKEN PATTERN & INTERVIEW - 12 AUG 2008 - TIRUPATI
Hi Friends This is Vamsi Krishna.
I attended the SASKEN placement drive held at Sree VidyaNikethan Engg College in Tirupathi on 12-08-08 and 13-08-08.
Four rounds--
Written
Technical interview
HR interview
Final interview
The written test was conducted in three sections, all in a single question paper.
SECTION1: English--It consisted of 2 passages,technical related. Also some bits on finding the right meaning of the highlighted words.
SECTION2: Verbal ability--It consisted of coding-decoding problems(very easy), some answering questions based given set of clues(tables).
SECTION3: C language and programming abilities--
25 questions,40 minutes.Some direct questions related to C,accurate output,finding program for given output.
After the test was completed a ppt was given and about two hours later the results were declared. Out of about550,120 candidates wer selected for the next round. I was one of them.
INTERVIEW
My interview chance came late in the evening. The technical interviewer was very friendly. The questions he asked were
1. how do you rate yourself in C between 1-10
I answered 6-7
2. (situation) If you were a passenger on a ship nd you came to know that a massive storm was approaching your way what would you do.
I advice you to think about this in your own unique way.
3. (situation) If you were an employee of SASKEN and one of your colleagues complains to your senior officials that you are not up-to the mark and also have poos skill sets, what will you do?
4. He told me to write down a structure along with its contents in C for implementing a linked list.
5. He asked some more questions from my resume
6. Favourite subject, Why??
I was then told to wait outside. I got the news that I was qualified for the next round. I entered the HR room about 2 hours after my technical.
The interviewer was very friendly. First she asked me whether I was feeling OK, nervous, etc.
Then she asked me to tell her something about myself.
Most of the time I was made to answer this question in an indirect way. There were some questions from my resume, especially form my paper presentation. The important thing was that we had to talk. My HR round lasted about 25minutes.
I was asked to wait outside. The final HR round interviewer called me in nd asked me if I was ok with the company with the company policies etc. She then gave me my congratulations letter, a kind of a call letter but an informal one.

The test comprises of 2 sections:
1. Technical ( C ) & Technical Subject- 60 mins, 60 questions
2. Logical Reasoning.. - 30 mins,17 questions....
==> Questions in C were mostly from "pointers in c" and "test ur C
skills" by Yeshwant Kanetkar... C questions based on command line arguments, data
structure ( BST, tree traversals). All the questions were like " what
is the output of the following program segment" and in many questions 3rd and
4th choices were (c) compilation error and (d) compilation, warning,
runtime error.... Heard they are asking abt- ptr, string, arr, preprocessor,
data structures etc.. C test was pretty ok pass by value, pass by reference
etc. questions were asked The general test was pretty tough, they ask u
fourier transforms,harmonics,Barkhuasen criterion,virtual memory,Whether FIFO
is better than LRU etc. 4 questions were from fourier transforms the
duration was 60 mins and no negative marking
C basics 10 questions ,very easy.Given a program and asked the
output-type questons.from pointers 3-4 questions are there. 2)reg subject:very very
easy:some from digital(on nand gates. Jk flip flop),from Information
theory and coding,some from Micro processors.
In Logical Reasoning all the 17 questions were paragraphs (argument) of 5 to
6 sentences...five sentences (choices) will be given below and questions were
asked like " which of the five if true will weaken or supports the argument
above .." :- R. S. Agrawal LR is sufficient
The questions were like this.

INTERVIEW EXPERIENCE:
Hi. I was one of the 12 people who were selected in the sasken campus drive at Sir MVIT Bangalore. I'm from computer science branch.
The interview process consisted of three rounds:
1) Online aptitude test
2) Technical Interview
3) HR Interview
1)Online aptitude test:
It consisted of four sections with 25 questions in each section. First three sections were Quant, Verbal And Logical Reasoning. Absolutely no preparation required for these sections. All questions were related to basic maths. But going through RS AGARWAL book will help. The fourth section was MCQs on 'programming'. nothing related to any specific programming language. Here your logical thinking abilities w.r.t programming are tested. If you are strong with basic concepts of any programming language then this section can be cleared easily. Although 'Test your C skills' book by Yeshwant Kanetkar helps.
Out of the 127 students who wrote the test only 27 cleared. Max filtering is done in the first round itself.
2) Technical Interview:
HIM: temme somethin bout yarself
ME: ...
HIM: what are your goals??
ME: ...
HIM: which is the subject you are strong at??
ME: C programming.
HIM: tell me any subject other than programming
ME: OS
Then he started asking questions about OS. Some of the Qs were like this:
>different types of OS architectures. . . (i had no idea! :P)
>What did u learn i OS
>tell me about processes
>about threads
>difference between processes and threads
>RISC and CISC (i said i donno)
Then he asked me to rate myself out of 5 in c and c++.
(if you tell 5 then they will screw the shit out of you!!. play safe)
Then he started asking some more Qs like:
>allocate memory for 2D array using malloc
>prog to reverse a number
>program to reverse a link list
>program to find if the link list is circular
>notations for finding efficiency of an algorithm (big oh, omega, theta)
Out of the 27 people only 12 cleared Technical round.
3) HR Inteview:
HIM: temme somethin bout yarself
ME: ...
HIM: what are your goals??
ME: ...
HIM: Y sasken?
ME: ... (listen to the ppt and tell stuffs from that)
HIM: y shud i hire you?
ME: ...
And some more commonly asked HR round questions.
HR round was just a formality. All those who cleared Technical round cleared HR round also. Finally results were announced and Welcome letters were given.
The process started at 9AM and got over at 10PM.
Its more than enough if you start preparing 3 days prior to the placement process.
Go through the basics from all the subjects from 3rd semester. and prepare for any one subject thoroughly since questions, in interview, will be asked on 'your' area of interest.
ALL THE BEST.

Sasken Communication Technology ltd - Pune, Feb 29,2012
Hi Friends
I am Ankur Bansal, I have done PG-Diploma in DIVESD from C-DAC ACTS, Pune in AUG-2011 batch after B.Tecg in Electronics & Communication. . I was selected in SASKEN during the campusing at C-DAC ACTS Pune held on 29th & 30th Feburary 2012. Here, I have tried my best to help you guys by giving information about the pattern used by SASKEN. There was no negative marking but there was individual cut-off marks for each section (in written round)
GENERAL PATTERN
1. Written test
2. Technical interview
3. HR interview
4. Personal Interview (just as a formality, in this part of interview they will ask, whether you agree with the bond or not and finally they will give you an offer letter).
1st round is totally based on online C programming test which contain 3 parts: beginner, intermediate and expertise. Question level increases as you move to beginner to intermediate to expertise.
Maximum question is based on file handling. This round is tough. If you clear this round then its easy for next round.
In Technical Round, as I was from ECE department and did Embedded course. they asked me most of the questions from embedded side and linux device driver and C & DS.
the questions were like
1) what is your aim in life?
2) what is difference between static and volatile class?
3) what is difference between structure and union & enum?
4) How dynamically memory is assigned in C.
5) some program based on linked list and stack.
6) what is difference between process, thread and task?
7) what is page fault?
8) what is semaphore, shared memory. Difference between semaphore and mutex?
9) What is the specific use of union in C i.e particular application of union ?
10) What is AVL & Binary Tree ?
11) How to see, total memory consumed by our C program ?
12) how to Play song and open web browser from C program ?
Around 45 min, interviewr asked such question and I answerd very clearly. After these basic
question interviewer asked me about my project for about 50 min.
In HR round they asked me the basic questions. So, just prepare some hr questions which are generally asked during the interview.
and remember one more thing, collect some information about Sasken (visit the website of sasken you can easily gather some information).
So, friends what I feel, once you clear the written round, there is a maximum chance to get selected because the rest of the rounds are not so tough. prepare the C, C++ part well. Finally I want to wish you all "BEST OF LUCK".

SASKEN PAPER & INTERVIEW - 15 OCT 2008
Hi Friends
I am Anuj Sethi, recently I got placed in SASKEN COMMUNICATION TECHNOLOGIES on 15th Oct. by God's grace..
A total of about 600-800 students appeared in the campus selection, out of which 66 cleared written then near about half of them were eliminated in Tech. interview and finally about half of them were eliminated in HR.
The selection process was divided into 3 parts:
1. Written Test (65 Questions in about 75 mins.)
2. Tech Interview
3. HR Interview
Written Test:
It was further divided into 3 categories (No sectional cut-off and no -ve marking):
1. English / Comprehensive part (15 Questions): This part includes synonyms, comprehensive passages etc. This part was not at all difficult and no preparation for this part is required according to me.
2. Verbal / Analytical abilities (25 Questions): This part was also easy and Verbal & Non-Verbal Reasoning by R.S. Aggarwal is enough to practice this part(however non verbal part is not required for SASKEN). It includes Syllogism/Logical Reasoning, coding-decoding, Puzzle test (a bit difficult) etc. I dun remember exact questions but m giving some similar examples.
(i) 3-4 questions were from Logic section from R.S. Aggarwal for ex:
(a) Some books are pens.
(b) Some pens are erasers and some options were given...
ans: none (coz both the statements were starting with "some")
(not exactly this question was there, but ya 2 of them were alike, as both the statements in them, were startin with "some")
(ii) about 5 questions were based on statement-conclusion. for ex:
Statement: All athletes do not drink.
(a) Mohan is a athlete.
(b) Mohan is not a athlete.
(c) Mohan drinks.
(d) Mohan do not drink.
options: (1) a&c (2) b&c (3) a&d (4) b&d
ans: (3) a&d
(III) 1 condition on Puzzle test (Family Based problem, type-6 puzzle test under R.S. Aggarwal) was given and 4-5 questions were based on it. it was a bit confusing and difficult, so practice these problems well else if you find it time consuming and still not sure about the result then skip this problem.
it was something like this: there are some family member: P,Q,R,S,T,U..
-->P and Q are either males or females.
-->R or S or both are males
-->T or U or both are females
(Q1) who is the son of S
(Q2) who is wife of P
(Q3) how many females are there etc...
(iv) 5-10 questions were based on coding-decoding. these were not too difficult to solve but practicing these will save your time.
3. Programming / C ability (25 Questions): This was most difficult part and you need to practice a lot for it specially on loops and on pointers other wise u can't do it.
Some of questions I remember were something like this:
(i) if there is a character pointer say *p having address 100, if we do p++ then what address will it contains
(a) 102 (b) 104 (c) 108 (d) 101
ans: 102
(ii) for given pattern what will b the correct algo:
11
12 22
13 23 33
14 24 34 44
some thing like this... and some algorithms were given and u have to choose the correct 1.
(iii) 4-5 questions were based on loop problems. A code was given based on loops (quite complex) and u have to choose the right output of it which was quite hard to derive.
Technical Interview:
(Experience and Questions asked)
All the interviewers were quite good so don't get nervous about the interview... just be confident and don't bluff at all if you don't know anything, rather try to divert interviewer's attention on the points/language/skills or subjects in which you are good, but do take care that in that thing you must be sound because after that they will ask each and everything about that particular subject. Like I said that my programming skills are good then he given me 2 programs to write and asked a lot about C++.
Firstly he asked about me and then about my aim... and to explain that...
C programs asked:
1. prog. to display prime no.s
2. prog. to display even no.s.
About C++ he asked me:
3. virtual pointers
4. runtime polymorphism with examples
5. to inherit 3 classes from a single base class in public, protected and private mode and also what is the scope and how data members and member functions of base class will b derived, used and their scope in inherited classes.
Also he asked me that what I meant or understand by telecom, I asked in what sense... he replied: like networks, what u understand by network or what telecompanies do...???
Also they can ask you about your projects in detail and other questions asked from my friends were:
1. to draw block diagram of microprocessor.
2. program to swap using function call by reference and value.
3. difference b/w structures and unions.
4. static and dynamic m/m allocation.
5. task scheduling.
6. multiple inheritance.
HR Interview:
Interviewer was a lady and she was very polite...the interview goes as following:
Lady: Tell something about yourself.
Me: ...bla...bla...
Lady: Tell about your family background
Me: ...bla...bla...
Lady: You have mentioned "adaptive" in your strengths...what do you mean by it and explain in what sense you are adaptive..?
Me: ...bla...bla...
Lady: support your answer with a live example...
Me: ...bla...bla...
Lady: any other instance or example that shows you r adaptive...
Me: ...bla...bla...
Lady: r u ok with the bond?
Me: ya, no problem...
-----then she signed the offer letter and handed to me----
Lady: congratulations Anuj!
Me: So am I selected mam?
Lady: yes!
Me: Thank you mam! thank you very much!!!
Me: Can i ask u one question mam?
Lady: Yes...
Me: Any negative point in me?
Lady: you should work a lil bit on your communication...
Me: k...thank you mam!
Me: Nice meeting you mam!!!
***For SASKEN you need to be good in Data Structures, Pointers, Computer N/W and programming skills.
***GuYs never underestimate yourself... I've done this after facing about 5-6 companies b4...
Always remember when God ordain luck for you... no-body can stop you!!!
Never loose your heart if u dun succeed rather try n try again until u succeed...

SASKEN PATTERN & INTERVIEW - 23 SEP 2008 - KOLKATA
Hi Friends
I am Ratnesh Kumar Jha from Murshidabad College of Engineering & Technology. I was selected in SASKEN during the pool campusing at TECHNO INDIA college (Kolkata) held on 23rd & 24th September. Here, I have tried my best to help you guys by giving information about the pattern used by SASKEN. There was no negative marking but there was individual cut-off marks for each section (in written round)
GENERAL PATTERN
1. Written test
2. Technical interview
3. HR interview
4. Personal Interview (just as a formality, in this part of interview they will ask, whether you agree with the bond or not and finally they will give you an offer letter).
Written test comprises of 65 questions having three different sections
1) English 2) Verbal & non-verbal reasoning 3) C & C++ questions
There were two paragraphs (5*2=10 marks) and Synonyms (5 marks).
IN reasoning part, there were 2 puzzles (5*2=10 marks) and the other questions were
from coding & decoding (5*1=5 marks) and logical reasoning (syllogism). i don't remember the rest.
In the C & C++ part, most of the questions were from pointers, functions, files, array, dynamic memory allocation (malloc based questions). the pattern of the question was to find out only errors or the o/p of the given program.
In Technical Round, as I was from ECE department they asked me most of the questions from my core subjects.
the questions were like
1) what is your aim in life?
2) which is your fav. subject? (I said microprocessors and networking)
3) what is the diff. bet. 8085 and 8086?
4) what are the no. of flags in 8085 & 8086?
5) details of flags.
6) why 8085 is called 8-bit processor and why 8086 is called 16-bit?
7) about address bus and data buss.
8) what is the difference between software and hardware interrupts?
9) what are the different layers in osi model?
10) difference between internet model and osi model ?
11) what is TCP and which layer it belongs to?
12) what is UDP and which layer it belongs to?
13) diff. between tcp and udp?
14) what is crossbar switching and strowger switching system?
15) diff. betwwen analog communication and digital communication?
16) what is the difference between structure and pointer?
17) how to create a structure?
18) what are the storage classes? explain register and static storage class?
19) write a program to swap the values using pointer?
20) how the memory is allocated in case of structure and union?
For the ECE students most of the technical questions were asked from microprocessor, networking, digital eloctronics, basic electronics and few questions were asked from C, C++.
In HR round they asked me the basic questions. So, just prepare some hr questions which are generally asked during the interview.
and remember one more thing, collect some information about Sasken (visit the website of sasken you can easily gather some information).
So, frnds what I feel, once you clear the written round, there is a maximum chance to get selected bcoz the rest of the rounds are not so tough. prepare the C, C++ part well. Finally I want to wish you all "BEST OF LUCK".

SASKEN PATTERN & INTERVIEW - 12 AUG 2008 - TIRUPATI
Hi Friends This is Vamsi Krishna.
I attended the SASKEN placement drive held at Sree VidyaNikethan Engg College in Tirupathi on 12-08-08 and 13-08-08.
Four rounds--
Written
Technical interview
HR interview
Final interview
The written test was conducted in three sections, all in a single question paper.
SECTION1: English--It consisted of 2 passages,technical related. Also some bits on finding the right meaning of the highlighted words.
SECTION2: Verbal ability--It consisted of coding-decoding problems(very easy), some answering questions based given set of clues(tables).
SECTION3: C language and programming abilities--
25 questions,40 minutes.Some direct questions related to C,accurate output,finding program for given output.
After the test was completed a ppt was given and about two hours later the results were declared. Out of about550,120 candidates wer selected for the next round. I was one of them.
INTERVIEW
My interview chance came late in the evening. The technical interviewer was very friendly. The questions he asked were
1. how do you rate yourself in C between 1-10
I answered 6-7
2. (situation) If you were a passenger on a ship nd you came to know that a massive storm was approaching your way what would you do.
I advice you to think about this in your own unique way.
3. (situation) If you were an employee of SASKEN and one of your colleagues complains to your senior officials that you are not up-to the mark and also have poos skill sets, what will you do?
4. He told me to write down a structure along with its contents in C for implementing a linked list.
5. He asked some more questions from my resume
6. Favourite subject, Why??
I was then told to wait outside. I got the news that I was qualified for the next round. I entered the HR room about 2 hours after my technical.
The interviewer was very friendly. First she asked me whether I was feeling OK, nervous, etc.
Then she asked me to tell her something about myself.
Most of the time I was made to answer this question in an indirect way. There were some questions from my resume, especially form my paper presentation. The important thing was that we had to talk. My HR round lasted about 25minutes.
I was asked to wait outside. The final HR round interviewer called me in nd asked me if I was ok with the company with the company policies etc. She then gave me my congratulations letter, a kind of a call letter but an informal one.

The test comprises of 2 sections:
1. Technical ( C ) & Technical Subject- 60 mins, 60 questions
2. Logical Reasoning.. - 30 mins,17 questions....
==> Questions in C were mostly from "pointers in c" and "test ur C
skills" by Yeshwant Kanetkar... C questions based on command line arguments, data
structure ( BST, tree traversals). All the questions were like " what
is the output of the following program segment" and in many questions 3rd and
4th choices were (c) compilation error and (d) compilation, warning,
runtime error.... Heard they are asking abt- ptr, string, arr, preprocessor,
data structures etc.. C test was pretty ok pass by value, pass by reference
etc. questions were asked The general test was pretty tough, they ask u
fourier transforms,harmonics,Barkhuasen criterion,virtual memory,Whether FIFO
is better than LRU etc. 4 questions were from fourier transforms the
duration was 60 mins and no negative marking
C basics 10 questions ,very easy.Given a program and asked the
output-type questons.from pointers 3-4 questions are there. 2)reg subject:very very
easy:some from digital(on nand gates. Jk flip flop),from Information
theory and coding,some from Micro processors.
In Logical Reasoning all the 17 questions were paragraphs (argument) of 5 to
6 sentences...five sentences (choices) will be given below and questions were
asked like " which of the five if true will weaken or supports the argument
above .." :- R. S. Agrawal LR is sufficient
The questions were like this.

Sain Bainuu,
ReplyDeleteSo bloody thorough! Ah! So happy and blissed out! I feel redeemed by reading out Sasken Interview Experience-1 . Keep up the good work!
I am trying to write a simple application in C that resembles the game "Computer Co", but I am stuck with this problem: If the board is represented by a dimensional array, with what algorithm could I tell if one player's pieces are captivated by the other's? In other words, how can I recognise whether the pieces of one colour form a circle?
Excellent tutorials - very easy to understand with all the details. I hope you will continue to provide more such tutorials.
Obrigado,
