Arm Project Manager interview questions

Very poor experience, the interviewers were completely unprepared and hadn't bothered covering the basics. They didn't know what role I had applied for, they didn't even know the place of work, I had applied for a role near the city I live, they were asking me if I would be prepared to move to Cambridge UK for the role! Very awkward situation and embarrassing really. By the way, nobody bothered getting back to me after the interview. I felt that I wasted my time preparing for the interview!
