Had online interviews with 6 interviewers in Jan, 2022. It took me ~3 hours in the morning. The interviewers included 2 engineers and 4 group leaders. It covered technical and behavioral questions. And, it was going well.

The whole process was remote (online). Phase 1: Intel recruiter emailed me to apply for this position as I had been referred internally by an Intel employee, whom I met at a conference (perks of going to conferences). Then received an email from a senior team member for a phone interview which was about 45 minutes long, or maybe an hour long. It was mostly like a conversation, and occasional specific questions about my Ph.D. research, troubleshooting experiences, etc. Tip - Be excited when you converse, show great interest in the company and the role. It is all about convincing them why they should spend an entire day knowing you more. Phase2: About a couple of days later, the hiring manager from the team emailed to set up a whole day interview which consisted of seven 1-1 interviews (with the whole team - engineers, group leaders, and senior engineering manager), and a 1-hour presentation on the PhD work. All the interviews mostly focussed on what I did during my PhD, what kind of research equipment I worked with, why I did what I did, troubleshooting, experience with the advisor, fellow grad students, conflict resolutions with lab mates and advisor, safety protocols, grasp on research methodology. Tip: Identify different situations from your experience to address questions on these topics and be ready to recall them when asked, a lot of questions will be asked. Time was given after each interview to ask questions, so prepare a lot of questions - about the role, company, team, etc. Phase 3: After the interview, received an email for a background check after 2 days which was a good sign, and finally got the offer after a week of the interview.

A long but friendly interview. Started with a phone screen from an engineer which lasted about an hour. A month later, I was contacted to schedule the panel interview. On the panel interview day, I had 6 interviews with hiring manager, group leaders, fellow engineers etc. and my own research presentation. Questions were mostly from my presentation and resume on how I solved each problem, why did I choose particular techniques etc.
