I ) . Written :Usually Wipro assigns 80 ques / 90 min . But I attended at my campus ,hence I had 50 ques / 50 min .
There are three section in Wipro's written :
VERBAL SECTION
Plz follow Barrons GRE from 11 to 15 th edition .including 5 model q-paper given at the last .
Just mug up the following things .1 Analogy 2.Antonyms 3.Sentence correction 4. Sentence completion
LOGICAL REASONING :
Dont follow the book "Quantitative & Aptitude " By RS Agarwall. Plz follow "Verbal & Non verbal reasoning " By RS Agarwall.And I found all the questions were of Logical reasoning type . Some questions are different like , octal-binary , bin-hexa conversion.
TECHNICAL SECTION
Study the following books for C questions .
1. Test your Skills in c.
2.Exploring C
3.Let us c
4. pointers in C
All the books are by Yaswanth Kanitkar Kanitkar .The following book is also usefull
1. The C programming Language by Dennish Ritchie .
IMPORTANT
You attend all the question without fail. Try for maximum . If ur written score is top , then they wont miss u even if u dont do the technical interview well. also go thro wipro's old question papers , bcause its possible that some
of the questions may be repeated .
I I ) Technical Interview
Most of the technical questions are from following areas .1 C , C++ ( Oops Basic concepts ) some times they may ask u to write codes and brainstorm u with pointers .Say ,
* Explain the working of printf ( ) and scanf () .
* whats function pointer and write the syntax.
* whats the difference between malloc() and calloc ( ).
* whats void pointer ? , null pointer ?[ like , some tricks in c .... ]
2.Data Structures ( searching , sorting , trees . But graphs are not considered mostly . ) .They will give u some data & u will be asked to sort out the data manually.also know about the no of comparison & computation [ like for Quick sort o(nlogn ) for bubble sort : o(n's square )] Also some times they ask u to write programs like ,
* infix to post and pre-fix
* Factorial using recursion ,
* swapping 2 numbers with out using the 3rd variable .
* syntax for binary tree
* program for linked list , double , circular lists .[ Just write anything , which may be wrong ! They just check for ur
confidence , they dont look at the code keenly !! ]
3. Operating System .
For this part , just revise ur subject ( bcause all of u could have already studied this subject) . Be sure of Memory management including Paging,Segmentation , also page replace ment algoritms , Process concepts ,scheduling alogorithms . Dead lock & prevention part is very very important .Dont miss to study the classical problem of dead lock including Dining philosopher problem , Producer consumer problem.
IMPORTANT :
os is very easy area . So u can easily impress the interviewer if u correctly produce the answers for ur Os questions . Give the suitable definition for each question. Dont baffle the things . Try to produce the answers by usking questions urself before u attend the interview .Say for example , the following questions cant have appropriate definition
in the text book !
* Whats External Fragmentation ?
* Whats Internal Fragmentation ?
* Whats the differnce between Linux & Windows ? [ U give bullet point
answers , Dont say like Windows is good , Linux is worst !!!!! ]
Mostly follow the books for Os ,
* "Operating System concepts by Silbertz Scatz "
* Modern Operating System by Andrew Tanenbaum.
4. DBMS
Revise the SQL [ u should be able to write queries ] , and study about the Normal Forms [1,2,3,4,5, with BCNf ], Joining Tables [left/right/full.outetr joining ],They some times ask about the integrities like domain , referential
integrity .Also be sure with keys like , Super, primary , candidate , Foriegn keys .For DBMS follow the book , " Data Base system concepts " By Korth .
5. Networking
Just know about the OSI stack and routing protocols and some thing about Ip classes .
ONE MORE IMPORTANT THINGS IS THAT , DONT USE UNWANTED TERMINOLOGIES.
Say for example , when u r asked to tell some differnce about Windows and Linux , if u say like , " Windows is COM based or Win32 API based........" . Then the next question will be "whats COM ? Whats Win32 API ?" .
So , use ur words very grisp and compact .[ I had this experience when I was answering . He asked me to tell about
the OSI layers , I was answering , at that time I used the word , " Incase of ATM network ....." , u know , he forgot about the OSI , and stared to ask from ATM . Then I told hime that I was not aware of ATM , and I could be
happy if he continue with the OSI layer again !!! ]
U CAN LEAD THE INTERVIEWER ! , Yes just make a boundary of questions saying that this is my interest subject , I will be happy if u ask more from this area . But say this after u tried for some questions .
Dont say I DONT KNOW !!! . Instead say like , " I am not much aware of it ! "
Prepare ur project [ if u have any mini project or ur final year project] . Atleat u must report about one project when u r asked to explain about ur project.when u r asked to tell about the project , u just give him an overview
like ,
* The project name is .... "xyz " ...
* This is used to .......
* This has these advatages .......
* I used these things ( like c , c++ ,Java ) in my project .
They will surely ask u to write some coding of some modules of ur project .[ I used SQL with Jsp in my-project . They asked me to write the coding for connecting JDBC with SQL ]. And explain ur role in ur project.
[ also I was asked to explain about my role in the project and tell about the major technical risk in the project and how I cleared the hurdle .]
HR interview .
U should be knowing a lot of ur-self at first ! since most of the questions are related to u and ur background .
Be preoared for the standard questions like ,
* Tell ablout ur-self ? [ or some time they will tease u like " who are u ?"]
* Tell me about ur family background .
* Tell ur strength and weakness ?
* Why should I hire u ?
* what do you know about Wipro ?
* What do you expect from Wipro ?
* Where u want be posted ? [ u just say anywhere ! ]
* Where do u find ur-self after 5 years ? [ Dont say I like to become an
IAS or IPS !!! tell some thing related ur professional life ]
* whats ur short-term goal & whats ur long term goal ? [ This answer should
match with ur pervious answer ! Thats why again they put the question using
different way !! ]
* Whats ur achievment ? or tell about ur co-curricular and extra-curricular
activities.
They will ask u a lot of cross questions when u r answering , so be patient
and give proofs to all ur points .I have some general tips to tell u all .
General comments
1. Keep a smiling face when u enter , that will let the tension to get rid off.
2. Dont speak too much ! and also Dont Give one line or one word answers .
3. Always speak cool . Dont expose that u r nervous / get tensed .
4. When u dont know answers for some questions , dont say " I dont know " .Instead , redirect the interviewer
saying that , " Sir I am not strong in that area , I will be happy if u ask questions from ...... [ the area
which u know well ! ]"
5.Dont keep mum for any questions , thats a very bad sign ! , Instead just track the session by speaking some related
things .
6. Dont use unwanted keyword / phrase ( which the mistake that I committed
and I explianed it above !!! )
7. Once u tell anything , plz stand by with ur answers , dont get back
ur words !!
8. Almost try to communicate using simple english and be sure that u got
the correct question also ur answer reached the interviewer.
9. Maintain a flow , thats , u maintain a gap of some jiffy between the
question and the answer .
10 . The one more thing is that , you believe that u r out smarted , ur
the ultimate , and have a gentle look with confidenc , then u will win !
MS SCHOLARS FACED IN PLACEMENT INTERVIEWS IN 1994 AND 1995
Wipinfo has 2 rounds of interviews. The first round is fully technical.The second round, depending on the members of the board, may betechnical,semi-technical or personal. Last year the second round was moretechnical than the first(!) and the board was headed by Mr. P.V.Sanjeeva Reddy, one of the no-nonsense, hardcore-technical, project leaders in Infotech. This year it was headed by Mr. Victor Jayakiran, G.M.(Technical, Global R&D) who was a much sober man and therefore spent most of the time in the second round dealing with personal questions.
I detail here the technical questions asked in the first round --
[1] Tell us about your work in brief.
My Ans. Mention first the title, followed by a brief overview of the work, what we plan to achieve, what has been achieved so far, finallythe relevance/scope of the work to the related area (i.e. how is it going to be useful). [ 5-10 mins. depending on interest of the listener.]
[2..n] Questions related to the work. Ans. Area dependent. [ 10 mins ]
[n+1] Tell us what you know about DMA and why that is needed?
My Ans. As usual, mentioned the wastage of CPU computation power spent in busy-waiting. Told how DMA
works.
[n+2] What are the various types of scheduling algo, what is used by UNIX?
My Ans. Mentioned Round Robin, First-come-first-served, Shortest-job-first, Earliest-deadline-first, Least-laxity-first,Priority-based-event-driven. UNIX uses RR with multi-level feedback.
[n+3] How can you implement SJF in UNIX?
My Ans. Usually, SJF means that we know the job-duration in advance. In UNIX where we cannot know that, we have to make assumptions about that based on which we should initially schedule. Periodically however, we
have to fine-tune our initial assumptions based on the times taken by various ready jobs, and recompute estimates and change the schedule accordingly.
[n+4] Different types of subroutine calling conventions?
My Ans. Call by value, reference, value-result.[n+5] Parameter passing sequence used by C?
My Ans. Rightmost parameter pushed first on stack.[n+6] What is a page-fault and how is it handled in UNIX?
My Ans. [Refer to MJBach, Ch. 9 for details].
Personal questions in the first round
1. What was your overall position in the Univ. in B.E.
2. Why did you choose to join MS here.
3. How do you like the MS course.
4. Anything you want to know about us.
Technical Questions in the second round
[1] What are the current trends and areas of focus in IT.
My Ans. Talked about emerging trends of S/W Engg and ISO 9000 stuff (gave vague ideas about them as I don't know much nor do I care about these topics myself ;-)). Then mentioned the proliferation of O-O methodologies and their usefulness in speeding up development process, code re-usability, ease of maintenance, ease of bug-fixing. Thirdly, mentioned the work going on in High-Speed N/w - FDDI, ATM, Fast-Ethernet(100Mbps). Told whatever little I knew about ATM in response to another question.
[2] What is a Micro-Kernel architecture.
My Ans. This is a developing area in OSs where instead of building the kernel as a single monolithic structure starting from scratch, it is built as a set of layers. The micro-kernel provides only the bare-bones like
Device-drivers, rudimentary filesystem support etc. on which, depending on the intended area of application of the OS, it can be customized to provide various higher level OS features like
Multiprocessing, IPC, etc.
Personal Questions in the second round
1. Tell us about yourself, your background.
2. What does your father do currently.
3. Your performance in schooling, B.E.
4. Your +/- points.
5. Why do you think Wipro should take you.
6. What qualities do you have that make you a person suitable for going
into the IT industry (a corollary to the previous question).
7. What do your friends opine about you.
8. When do you think you will complete and be able to join.
9. How can you assure that you will join by that time.
10. Anything you want to know about us.
________________________________________
Wipro Infotech
FIRST INTERVIEW:(First the interviewer asked me to name two favorite subjects - OS and Networks)
a) Describe the memory management policies in Unix. How is paging implemented? How page faults are handled?
Seems to be a favorite question for these chaps ---- Maurice Bach.
b) Write a macro in C for swapping two nibbles in a byte.Use the shift operators and be careful while defining
temporary variables( if you do so) as you have to write a macro. Otherwise it is pretty simple.
c) What is the CPU-scheduling policy in Unix? - Round robin scheduling with multilevel queues.
d) Diffrence between short term, long term and medium term scheduler.First two should be peaceful. The last one
is also known as swapper. (See Taenenbaum and/or Peterson)
e) Name various page-replacement policies. Which can be implemented both with and without pre-emption? - see
Peterson.
f) Describe the Sliding window protocol. What is it's advantage over stop-and-wait? - Saves bandwidth.
(Taenenbaum please)
2ND INTERVIEW (Both personal and technical interleaved)
a) Tell us something about yourself.
b) Aren't you going for higher studies abroad? Why?
c) Rank and CGPA. MSites do not have ranks but still they wanted to know my approx position in my batch.
Shady question. It is your job to convince them that for MS, grades do not hold any meaning.
d) What is re-entrant code? --- Non-self modifying code. Can be shared by many processes simultaneously.
Gave e.g. of text-editors like 'vi'. Counter Q: But then no code modifies itself. What does 'non-self modifying'
mean? ---- I don't know for sure.
e) Diff between compilers and interpreters. Some fundaes about how to link code in different files.
f) What would your friends tell us about you if we ask them? Standard question for everyone.
Company: Motorola (came in August'95) Just one question: When do you expect to finish? ---By August'96
That is too late. We are looking for guys who finish by Jan'96. Pl. apply a month before you
submit your thesis. Thank you very much.

WIPRO INFOTECH Ltd.
I don't think there's anything to be said about these giants. Only thing is, Wipro is not into the holidays business. I firmly believe that joining Wipro will further your student-like life for a few more years, and if you are really raring to get into the corporate line of jobs, then Wipro is not for you. When I say Wipro above, I mean Infotech. Wipro Systems is one of the more Pseud-ish companies, what with their formal attire, replete with Tie and associated
appurtenances of a western lifestyle. Both Wipro-s have a very good pay, and *sure-shot* revisions once a year, where you do end up getting at least a 20% hike, usually. Don't quote me, however. This is strictly off the records.

TECHNICAL INTERVIEW :
The interview was to some extent a bit tough. For others the interview was over in 30 min but in my case I had to give an 1 hr straight interview, that was because of me only as I had explained the interviewer my project thoroughly.. Initially the interviewer took a CPP book of Balaguruswamy and asked me 20 CPP questions at a stretch, I could answer about 16 of them.
Some of the questions were :
1) Difference between structure and class.
2) How to resolve ambiguity in multiple inheritance ?
3) What is static and dynamic binding in C ?
4) What is the difference between structure and array?
5) Difference between calloc and malloc & realloc?
6) What is static class and static member function?
7) What is pointer to a pointer? How it is declared and how is it accessed?
8) What is the difference between function overriding and overloading ?
9) What is the scope of a variable ?
10) What is the difference between C & C++ ?
11) Some questions on templates and exceptions.
12) What is stream ? How is it opened and describe file handling in CPP?
Others I don’t remember..
Some questions related to Hard Disc :What is a hdd? How is a file accessed from the hdd? Why isn’t it used in place of a RAM ? What is RAID describe its basic structure ? . Where is the file information stored on the hard disk ? What is FAT ? How are files physically arranged on the hard disc?
What is JVM, what is BYTE CODE ? What is multithreading ? How can it be implemented using C, write a program to describe it? What is the complexity of radix sort and how is it determined? A sequence of 15 numbers was to be sorted using heap sort. (He stopped me after the 3rd iteration).
Some questions related to JavaScript, dynamic HTML, static HTML, ASP, .NET A query on natural join in SQL, what is the need of normalization ? What is data inconsistency and redundancy? What is the basic difference between file systems and database systems? What are triggers and assertions in SQL? How can you use C to connect with Oracle SQL database? (Using Oracle 8i PRO C/C++ precompiler )A complicated query on a trigger. (which I couldn’t ans).
What is fork system call? How is a child process called and what happens to the parent ? In C what is spawnv () function, describe its execution. How can you use C for writing assembly language programs ?
If you have done any project then try to bring the discussion towards it. I was interviewed on the project for about 20 min and I kept on explaining till he took up the HR form and signed it!!!! The interviewer was very impressed with my technical knowledge and gave his feedback to the HR interviewer as “Very Confident & sound technical skills”. (I had overlooked the remark when he was writing it !!!)
HR INTERVIEW :
I was initially asked to describe myself. Since I had presented four papers in different places in India I took his attention towards it by telling that one of my hobbies is public presentation, and I supported it with example . He asked me about each and every paper and I took 45 min to explain him all the papers. Then he asked whether I wanted to know anything about WIPRO. I asked him around 11 - 12 questions and he was pretty impressed. The trick was to just to nod ur head and frame the next question in line while he was explaining one question.
Some of the questions which I asked were :
1) WIPRO has undertaken a project named “ MOBIO” it deals with biometrics. Since our minor project is on fingerprint recognition I would like to know something about MOBIO.
2) After gaining the billion dollar status Mr Azim Premjee said that appreciation of rupee is a concern. What should be the possible steps so that it no more remains a concern?
3) U have diversified from soaps to software as well as maintained a constant growth rate. What is the secret of ur success?
4) The work culture at WIPRO is great. How do u maintain it?
5) How do u allocate projects among ur employees?
6) How do u select employees for foreign duty?
7) What is six sigma strategy and how do u implement it?
8) In the expression “WIPRO is a CMMi company” , what does ‘i’ signify?
9) Is SAP associated with you someway ?
10) Do you have plans to design a μp better than Pentium 4? (They were the first in India to develop 8086 chip at IISc Bangalore , so I took this chance of asking him the silly question!!!)
And others…..
Then finally he asked if I had any preference regarding place of posting and whether I had any problems signing the bond of 15 months ? They are providing a salary of 18,000/- including perks to CS/IT/ECE And 17,000/- to core branches. Training is at Bangalore and is of three months then permanent placement.
Hope my efforts of downloading these questions from my brain would be of some help to You. I wish you all the very best of luck and thanks to all those well wishers who had helped me by sending recent and old papers of WIPRO (specially guys from NIT Durgapur and JU,NIT Trichy and others which pardon me I don’t remember, Thank you very much )

WIPRO TECHNOLOGIES (MANIT Bhopal )
3rd/4th May 2004
Hi every buddy,
The selection process in WIPRO was really cooool and I sailed through it to finally get a selection. As asked in Jadavpur University, Kolkata, here too the paper consisted of three sections 1-15 Verbal (Read Barron’s test papers & the exercise questions ) 16 – 30 Analytical reasoning . 31 – 50 Technical. The only difference between JU and our’s was that they were provided 50 min to ans the questions but we were allowed 60 min. There was individual cut-off for each section. In case of IT/CSE/EL the cutoff was 7,7,12. For other core branches it was 4,6,6. 360 people actually sat for the written test. 181 were short listed. There was a technical interview which one needed to clear in order to sit for the HR interview. Around 105 cleared the technical interview and finally 84 were selected among the lot. In our case HR eliminated about 20%. IT –14. CSE – 24, ECE- 29, CIVIL – 2, MECH – 2, ELECTRICAL – 6, MCA - 7 The Verbal section was really tough for people like me not preparing for CAT and GRE.
VERBAL SECTION :
Well , the first eight questions were word pair analogy. I couldn’t just make any analogy as such from them barring a few. The pairs were so typical that currently I don’t remember. Practice hard Barron’s just mug up if u can’t find the analogy.3 questions were from Barron’s.(model 5 test paper’s 15 and 13th question )If you have good command over ur vocab it would be easier for you. The other 7 questions were fill in the blanks they were pretty easy and any layman can get through. A sentence with two missing words was given and among the four options u need to choose the correct one. According to my friends my score in this section may be eight or nine(the worst among all the three sections )

ANALYTICAL SECTION :
This section was really easy and almost as clear as water for any person preparing for CAT. Every question had four options from which we had to choose the correct answer. Some of the questions were :
1) A,B,C,D,E ,F are to be given adjacent rooms .The rooms don’t have complete walls between them rather sound, smoke can easily get through from one to another as there are gaps over a wall for free exchange of air. Miss C the head is allotted room no 5 as wished by her. Miss E needs a telephone for regular communication. Mr A & Mr B prefer to have adjacent rooms. Mr B,C,D are chain smokers. Miss C is allergic to cigarette smoke.

If Hrithik is selected Maniratnam is also selected and vice versa. What should be the team if Amitabh is selected ?Four options..
4) H = A+B –R , F = H + I , T = F + A – C+ D , S = T/2, R = A*S; If F is to be derived what is also needed to be derived ?

a) three girls , b) two boys and the lady c) the man, woman , one boy, one girl d) two boys, woman and a girl.
6) A series of drama is to be arranged on all the five days of the week. Monday to Friday. Drama contains fiction, romance, horror, comedy, tragedy. Horror cannot immediately precede romance , fiction should be scheduled earlier than romance , comedy should come after tragedy. If Horror is arranged on Friday then what should be the sequence of the dramas.(NB there may have been other conditions in this examples which I presently don’t remember )
7) Three ice creams are to be made available every day by the college canteen. The IC available are strawberry, butterscotch,vanilla,choco, mango, choco-vanilla, pineapple. Each day should have ice creams which was also present day before. All the icecreams can be repeated only thrice during the entire week .IF choco, vanilla ,straw berry is given on Wednesday .

If E is selected B should not be selected. What is the team?
Among the above two questions were repeated giving different names that makes it 10 questions which I have provided you. I am sorry dear I don’t remember the other 5 questions. I had correctly answered almost 14 in this section.

Rest of the questions are at large out in the blue.... perform a quicksort and then do a worst case binary search to get them...
I could answer correctly about 16 questions in this section.
TECHNICAL INTERVIEW :
The interview was to some extent a bit tough. For others the interview was over in 30 min but in my case I had to give an 1 hr straight interview, that was because of me only as I had explained the interviewer my project thoroughly.. Initially the interviewer took a CPP book of Balaguruswamy and asked me 20 CPP questions at a stretch, I could answer about 16 of them.
Some of the questions were :
1) Difference between structure and class.
2) How to resolve ambiguity in multiple inheritance ?
3) What is static and dynamic binding in C ?
4) What is the difference between structure and array?
5) Difference between calloc and malloc & realloc?
6) What is static class and static member function?
7) What is pointer to a pointer? How it is declared and how is it accessed?
8) What is the difference between function overriding and overloading ?
9) What is the scope of a variable ?
10) What is the difference between C & C++ ?
11) Some questions on templates and exceptions.
12) What is stream ? How is it opened and describe file handling in CPP?
Others I don’t remember..
Some questions related to Hard Disc :What is a hdd? How is a file accessed from the hdd? Why isn’t it used in place of a RAM ? What is RAID describe its basic structure ? . Where is the file information stored on the hard disk ? What is FAT ? How are files physically arranged on the hard disc?
What is JVM, what is BYTE CODE ? What is multithreading ? How can it be implemented using C, write a program to describe it? What is the complexity of radix sort and how is it determined? A sequence of 15 numbers was to be sorted using heap sort. (He stopped me after the 3rd iteration).
Some questions related to JavaScript, dynamic HTML, static HTML, ASP, .NET A query on natural join in SQL, what is the need of normalization ? What is data inconsistency and redundancy? What is the basic difference between file systems and database systems? What are triggers and assertions in SQL? How can you use C to connect with Oracle SQL database? (Using Oracle 8i PRO C/C++ precompiler )A complicated query on a trigger. (which I couldn’t ans).
What is fork system call? How is a child process called and what happens to the parent ? In C what is spawnv () function, describe its execution. How can you use C for writing assembly language programs ?
If you have done any project then try to bring the discussion towards it. I was interviewed on the project for about 20 min and I kept on explaining till he took up the HR form and signed it!!!! The interviewer was very impressed with my technical knowledge and gave his feedback to the HR interviewer as “Very Confident & sound technical skills”. (I had overlooked the remark when he was writing it !!!)
HR INTERVIEW :
I was initially asked to describe myself. Since I had presented four papers in different places in India I took his attention towards it by telling that one of my hobbies is public presentation, and I supported it with example . He asked me about each and every paper and I took 45 min to explain him all the papers. Then he asked whether I wanted to know anything about WIPRO. I asked him around 11 - 12 questions and he was pretty impressed. The trick was to just to nod ur head and frame the next question in line while he was explaining one question.
Some of the questions which I asked were :
1) WIPRO has undertaken a project named “ MOBIO” it deals with biometrics. Since our minor project is on fingerprint recognition I would like to know something about MOBIO.
2) After gaining the billion dollar status Mr Azim Premjee said that appreciation of rupee is a concern. What should be the possible steps so that it no more remains a concern?
3) U have diversified from soaps to software as well as maintained a constant growth rate. What is the secret of ur success?
4) The work culture at WIPRO is great. How do u maintain it?
5) How do u allocate projects among ur employees?
6) How do u select employees for foreign duty?
7) What is six sigma strategy and how do u implement it?
8) In the expression “WIPRO is a CMMi company” , what does ‘i’ signify?
9) Is SAP associated with you someway ?
10) Do you have plans to design a μp better than Pentium 4? (They were the first in India to develop 8086 chip at IISc Bangalore , so I took this chance of asking him the silly question!!!)
And others…..
Then finally he asked if I had any preference regarding place of posting and whether I had any problems signing the bond of 15 months ? They are providing a salary of 18,000/- including perks to CS/IT/ECE And 17,000/- to core branches. Training is at Bangalore and is of three months then permanent placement.
Hope my efforts of downloading these questions from my brain would be of some help to You. I wish you all the very best of luck and thanks to all those well wishers who had helped me by sending recent and old papers of WIPRO (specially guys from NIT Durgapur and JU,NIT Trichy and others which pardon me I don’t remember, Thank you very much )
