There were five panels roughly 45 min per person. Each person went through a different topic of ASIC design. Make sure to have solid fundamentals. The questions really focus on the basics.

1 round with recruiter, 1 round with manager, basic resume review, 4 rounds technical, could be more efficient as a panel. Had interview rescheduled without really checking in or asking. One interviewer failed to show up, no answer from follow up, very disappointing from an established company. Felt like my time was not valued.
