aptitude : easy quant. technical : had 2 sctions of 30 mins each. Section 1 had 10 simple questions based on c/c++. few
algorithms were asked, eg. binary search tree depth. Most questions were from denis - ritchie. Sect 2 was general computer
science. had questions on 2's complement, logic gates, graph algorithms etc.

Most of the emphasis was on C, OS and ds. there were 3 tech interviews questions included virtual functions, virtual
memory, segmentation and paging, stack code, dictionary searching, a few puzzles like the 1 km north-east-south. The
questions were simple, concept based. Hashing was also asked frequently. Questions on internship were also asked.

HR interview was very easy. I was shown the ppt again. lasted only bout 20 mins. questions were mostly about the family
background. also what i thought about IBM(were i interned).

Concentrate on C. completely read denis-ritchie. Solve simple puzzles, the wu site easy/medium would probably be
enough. In Ds, be confident on hashing. Most questions wil be standard, what will be available online.

Overall the selection process was very simple. only 4 ppl cleared the written. out of these 3 were selected. Regarding the
company, the HR presented a very good impression. Work being mostly in C, with region specific teams.
