First Round:

It was a telephonic interview that lasted around 30-45 minutes. The interviewer discussed my project from the resume and later asked some follow-up questions about it. Other questions covered setup time, hold time, the difference between a latch and a flip-flop, and basic digital design concepts.

Following this, I was invited for an on-site interview.

Gave me a waveform of a state machine and asked me to draw the state machine from the waveform.

Asked me to draw basic digital design circuits, including sequential circuits based on some conditions.

Discussed setup time, hold time, timing equations, skew, and the ASIC design flow with a brief description of each process.
