I applied online. I interviewed at Arm (London, England) in Jul 2018
Interview
Over all it is not too difficult. Some unexpected questions such as the schematic diagram of some digital gate. But they give me enough time to derive the result. It was alright
I applied through an employee referral. The process took 4 weeks. I interviewed at Arm (Chandler, AZ) in Sep 2015
Interview
It started with phone screening by the hiring manager. Then on-site interview paid for by Arm. The on-site interview was with five different people. Mostly involved technical questions and occasional behavioral question. Decision was made fairly quickly within a week.
