Arm Project Manager interview questions

I initially interviewed for a different project manager position a couple of months before this one, where I was interviewed on Skype. I received quick feedback that although I interviewed well, I wasn't seen as a good fit for the position, but I would be considered for future project management positions. I was contacted regarding this position, and asked to attend a face-to-face interview in Loughborough. The fact that I was kept on record for future positions, and received quick feedback was very impressive. The interview itself consisted of three consecutive one-to-one interviews; one with a hardware manager, one with a software manager, and one with the line manager (a programme director). I found out later this would have been 4 interviews, but the research manager was ill that day - this is a very thorough interview process. Due to the timing of the interview, lunch was provided, which was again, a very nice touch. The interview(s) in total lasted around 3.5 hours. I was questioned on my past experiences, things that had gone well and gone wrong, strengths and weaknesses and that sort of stuff. In addition to this, I was asked to explain my understanding of the design processes that were followed, how I would solve various challenges, what risks I saw in some example scenarios and my thoughts on a number of technical and non-technical issues. The interviews were conducted in a relaxed and friendly way, and I was given plenty of opportunity to ask my interviewers questions. I was given a brief tour of the site as well, and more information on the role, as well as an indication of a decision timeline. I received an offer within a week of the interview, which I gladly accepted. Overall, a great and impressive experience, where I was kept informed throughout, and one which I would highly recommend to others.
