One phone call from the team lead. Asked about the projects and course work. It was more like a casual technical round. Lasted for about 45min. Second phone call on the same day was from the principal designer of the team. Asked more in death technical questions. 60min.

Initial phone screening (some questions on resume and mostly verilog questions) followed by onsite interview with 4 people (half hour each) general HR questions, state machine problem, timing related questions, verilog coding.
