totally had 2 rounds, met them in university career fair. First round was both behavioral and technical, second round was fairly technical. The questions were easy. communication was good and they responded almost immediately to all the mails which I had sent. The questions asked were fairly basic ranging from problems in op-amp to CMOS. The second round had questions from flip-flops and shift registers. they were again simple and easy to solve.

Basic digital design, clock domain crossing ,fifo for analog prepare rc circuit. keep your basic clear and dont try to make interviewer fool. Approach to problem is checked rather than answers.
