Razorthink Software Development Engineer interview questions

The interview process was two days. The first day they conducted an aptitude test. I cleared the aptitude test successfully. And they held the interview rounds for the second day. Round 1: Tech interview 1 They asked me all sort of questions ranging from data structures ,java,oops,SQL,programming and pointers. They were very tough questions. I couldn't pass this round. Round 2: Tech interview 2 They asked about project. Round 3: HR interview Overall i was a bad experience for me.
