    Along with this paper you would be given 4 topics(ESSAY WRITING).Here we have to chose one topic and write an essay.i wrote on “PARENTS ARE THE BEST TEACHERS”

    The results were announced in half an hour..I was shortlistd for the secod round.The next round was Aptitude Test.

    2. 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. I was shortlistd for the third round (JAM)..

    3. JAM (COMMUNICATION TEST)

    Here ,we were given a topic and to speak on that for about a minute. My batch had “SOCIAL RESPONSIBILITY”. Other batches had “ROLE MODEL”, “3 IMPORTANT PROBLEMS OF INDIA”. Unfortunately, HR was unimpressed with my speech. But,frnds talk loudly,with confidence.Express your ideas with a clarity in your ideas.Dont take lite,as this your chance to show who you are.So,try to give your best shot.. Dont pause.Keep a smile on your face.Around 22 were shortlistd for the TECHNICAL INTERVIEW round.

    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.

    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.
