I applied through a recruiter. I interviewed at Cirrus Logic
Interview
Recruiter, then phone interview, then onsite interview. The interview took a full day with more than five groups of people. Each group had two people. We had lunch with everyone.
Applied online and got a phone interview in 2 weeks, the interviewer was nice. Average difficulty questions. No offer at the end because they wanted somebody with more industrial experience
Interview questions [1]
