There are two technical rounds followed by a HR round which is the last round. First round will be taken by someone who is less experienced and second round by someone who is an experienced candidate.

We had first round as aptitude round (it was very easy and puzzles was involved), next was group discussion(about 10-12 people per group and my topic was on technical skills vs communication skills), then technical written test(sql queries were asked), in person technical round(again sql round and projects), another technical round, hr round
