One phone interview by two of the research engineers in the their group. They first introduced what they do in their group, then mostly asked questions about the research projects I put on my resume. We had some very technical and deep discussion about the performance/energy tradeoffs of some design decisions. They are very flexible in terms of what projects to work on.

Applied online, telephone interview and onsite interview in Cambridge. The interviewers are very friendly. The on-site interview contains a presentation regarding the role and the interviewer asks questions in the process of it. Relax environment.
