Arrived at the buildings, no other interview candidates and waited around 10 mins past scheduled time for the interview. Led to a small room and had 2 interviewers, one china and one uk. Both were pretty senior engineers. Was asked normal questions of why arm, then almost immediately jumped straight into the technical questions They had a list of questions to choose from and they randomly picked Frist was about transistors and circuits - fairly straightforward. Second was about the master slave relationship for writing a file Third was how to draw a processor. I found they kept asking stuff until you didnt' know, to test the depth of your knowledge

Online hirevue interview (30 minutes) which consisted of a handful of pre recorded questions, and face to face interview over zoom (2 hours), which consisted of 3 engineers interviewing me, asking problem solving questions and questions about my CV.
