The 1st Round is the quantitative aptitude and reasoning. The 2nd Round is the technical aptitude. I have done both at a time one after the other. After the results 7-8 candidates moved to the technical round(including me). In the technical round i was asked questions on geometry and engineering drawing. After the interview the interviewer told me if i get selected for the other rounds i would be getting a call in 1-2 Weeks. The company chose other candidate.
