Interview
Online interview via Hirevue, most questions are competency-based questions
There's also one coding question where you get to choose the programming language, it takes you to another windows where the interface is sort of like an IDE you use for coding
I applied online. The process took 3 weeks. I interviewed at Arm (Cambridge, England) in Oct 2016
Interview
I applied online. They sent me a link to a website on which I was supposed to record myself answering their questions. There were 10 minutes per question. They were HR related. At the end there was a programming challenge, a very easy one. After a few days they invited me to an assessment day, where I had a technical interview about computer architecture and projects on my resume. There were also some exercises in groups meant to allow them to observe our interaction and team working.
