I applied online. The process took 2 months. I interviewed at Arm (Londres, Inglaterra) in Feb 2021
Interview
Two interviews: one being recorded and one in-person. You will be invited to the in-person one if you pass the recorded interview. Both require strong technical knowledge. Be prepared to answer questions about what arm does as well.
Video interview over Hirevue. Primarily technical questions, such as what you did the last time you encountered a bug, as well as a programming challenge, requiring you to explain your solution.
First round is a Hirevue interview which is followed by a call with people representing different sectors at ARM. The call can be quite intimidating because of the number of people but they are very nice. If you know your stuff, you'll be fine.
