Infosys Placement papers 2007
There are three section in Wipro?s written :
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.
Study the following books for C questions .
1. Test your Skills in 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 .
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) 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 ?. ]
( 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.
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.
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 .
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 .]
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 .
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 !
