Interview process is easy first round is aptitude then there is one on one technical round (the people clearing 1st round) Then after that there can be one more technical round and then last round with VP and GM.

First aptitude of english and quant, even a 5th class child can solve it. Then after interview of silly technical questions, they just do time pass with you asking question like why don't you become IAS. Next round is of HR which has some illiterate boss who does't even know how to speak.
