I applied online for this job and was contacted to do an on-demand online interview after 10 days. This first step was a short interview with around 7/8 questions about both technical and personal aspects. Second step of the hiring process was to take part to a selection day in Cambridge at ARM which consists of several tasks to test you individual and group skills and a technical interview which lasts about 1 hour.

To be honest the on demand was bit harder for me because I felt more pressure when answering the questions. I think it's a psychological thing due to the counting down timer that you see while recording your answers.

On the other hand, I really enjoyed the whole day at ARM for the selection day. Every single person was very kind and ready to answer all of your questions. I didn't feel any pressure at all while doing the technical interview, time just flew, it was like talking with a friend.
