I applied online. The process took 2 months. I interviewed at Arm (Fulbourn, England) in Jan 2015
Interview
Initial HR phone call, followed by a pre-screening written task and two face-to-face interviews both with the line manager. The first was with a peer and the second was with the senior line manager
Interview questions [1]
Question 1
The written task listed several tasks the role would typically encounter and asked for your views on them.
Both interviews focused on how you'd address day to day and longer term strategic challenges and personal preferences on how you came to those conclusions. These were fairly detailed and drilling questions.
