It's a 3 round process.
1) aptitude:
There where 4 sections with 2 subsection each. This round covered all basics including quants,verbal,logical and basic computer related topics(c,c++,java).
2) face-to-face interview:
It was technical interview, purely based on the panel. I mainly had questions from my Resume and some basics from area of interest specified. Being confident with what you know and conveying it clearly will help you.
3) HR:
Typical HR round like family background, shift timings. Also questions were asked to test communication skill and how well you think and give relevant response to scenarios being asked.
