Here are some information that I present , plz have some patience & read
the complete mail .wipro has 3 modes of selection .1. Written test 2.Technical interview 3.Hr interview .I have also given the details of books which mostly refered .
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 !
