IBM GBS came to our college on 6th August. The selection procedure has 4 rounds--
1. Aptitude test
it had 3 sections:
First section was on matrices. 15 qs with time 12 mins (no negative marks). it had 3 5x5 matrices. then there were 5 qs from each matrix.... all qs were of reasoning type, something like if rows 2 & 4 are interchanged, what is the 3rd element in 3rd column. Then, start at a particular element say upper right corner, follow certain directions and say the element u arrive at.. replacing one symbol with other and qs related to that.. easy enough... just have to be fast in cracking those sums...........
Second section was related to number series. 20 qs with 4 mins time(1/4th negative marks). Series were easy enough, but u have to be really quick. some sequence of numbers will be given, u have to identify next one in series
Third section was arithmetic,12 qs with 15 mins time (1/4 negative marks). problems were from time&work, interest, time, dist&speed.somewhat easy, though u have to do calculations really quickly
2. Essay writing
u will be given 15 mins to write an essay. our topic was "politicians should be honest". They just want to see whether u have the capability to clearly write ur thoughts. Wont be a major hurdle as essay writing will be evaluated, if at all, during interview.
out of 120 odd students, 52 cleared aptitude test
we were divided into groups of 10 and then there was a gd. topic was "love marriage is better than arranged marriage". they will give 10 mins for open house, then 30 secs at the end 4 each one to express his views. It is a selection rather than rejection round. So, if u speak up in gd, u will almost be through to next round.
43 cleared this round
hr and technical will happen simultaneously. it lasts 4 abt 30 mins per person. not very difficult though. Just remember to be confident and keep a smile on ur face. They will be friendly. at last, 32 cleared
