Two rounds. First round was a 30 min interview on basics (BJT, FET etc.) they were also keen on knowing if I did my research in the job position and about the company. Second round of interviews was a much elaborate one. PhD work was presented (45 min presentation and 15 mins QA session) which was followed by 6 one-on-pne interviews. Mostly technical.

Interview was conducted one time at the local recruiter office by a panel of screening team, and one more time thru phone by the hiring managers in the Newbury Park, California. After that, I was flown to NBP for site visit, meeting with the teams, and training. Overall very pleasant hiring experience.
