Hi frnds…I’ve attenaded the CSC recruitment which held in BITS,warangal through JKC..i am shiva from CSE.The recruitment process is as follows:
- Presentation
- Technical test and Aptitude Test.
- JAM(JUST A MINUTE)
- TECHNICAL INTERVIEW
- HR INTERVIEW
PRESENTATION
In the presentation,the company had made a brief introduction of their firm , with selection process details and job profile and so on..It lasted for about half an hour or so…
1. TECHNICAL & APTITUDE TEST:
First,they gave the technical paper to solve..It consistd of 75 qstns to be solved in 40 minutes.It was like a piece of cake for me to solve the paper.plss read the qstns and answers which i give and all are right answers…prepare previous papers ,its enough..and aptitude paper consists of 40 questions in 40 mins.tech paper is very easy….but aptitude is tuff……prepare aptitude……… the tech paper is asa follows

. APTITUDE TEST:
This paper consists of 40 qstns to be solved in 40 minutes.This section was moderate(not so difficult).
–>One qstsn was on propabiltity like there are 3 piles of books.Each containing 6,5,4 books.What is the propability that first book will be arranged and so on.. ans: 12!
—>One qstn on profit and loss..
—>one qstns on speed and distance.
—>there were 3 fill ups with suitable words. (easy)
—>there were 5-6 passages (all easy)
—>there were 3-4 analogies.
—>one qstns on permutation.
—>one qstn was on ages..
—->two qstns were from ratios.
—->Then one one problem from geometry containing 3 sub-qstns.(See BARRONS GRE.it would be helpful)
—->One function like f(0,x)=x+1
f(0,y)=y
f(0,0)=1
f(x,y)=f(x+2,f(y-1))(not the exact qstns but similar like that) then find f(1,1),f(3,0).f(1,2),then derive f(3,0) in terms of f(0.0),f(1,0),f(1,2).Totally 5 sub qstns ..all were easy..
—->One Sudoku problem..A 3*3 block in which only 2 blocks were filled.The remaining bloxks had to be filled such that diagonally,vertically, horizontally it should sum up to 15..based on this 5 easy qstns were given..
The results were out.total 951 students attented the test in that 370 selected for next round. I was shortlistd for the second round (JAM)..
3. JAM (COMMUNICATION TEST)
Here ,we were given a topic and to speak on that for about a minute. My batch had “TECHNOLOGY vs AGRICULTURE”. Other batches had “ROLE MODEL”, “WOMEN IN SOCIETY”,”3 IMPORTANT PROBLEMS OF INDIA”, “TELL ME ABOUT UR SELF”. my batch consists of 20 members.3 cleared the JAM round..luckly i am one among them…….MAXIMUM elimination is here……bcarefull guys……………..
4. TECHNICAL INTERVIEW
Be confident with ur basic skills (C,C++).If you are of ECE be confident with your core knowledge.It helps you a lot.Be cool as much as you can.i am from CSE…the questions asked is
1. tell me ur project?
2.primary key?
3.normailsation?
4.double linked list?
5.IP adress?
6.diff between TCP and UDP?
7.bubble sort?
8.different types of databases?
9.basics on .net(i used .net technology in my project)
10.unix?
i done extremely good in this round………i got 4/5 rating………and i qualified for HR round
5. HR INTERVIEW
It is a normal round checking your communication skills and your personal skills.Be bold and confident.You would definitely go through this round. no questions for me in this round……….because of my percentage and tech round score….directly HR said that “U R SELECTED FOR CSC” ………….PREPARE WELL .May GOD bless you..
