After meeting ARM engineers at a job forum, I applied for Graduate jobs at ARM. Two weeks later, I was invited to the Sophia Antipolis center for the interview process. The first hour began with a quiz, then I had many 1:1 interviews. The questions of the quiz are not difficult, you just need to know the basics of C, VHDL/Verilog, micro electronics and computer architecture. During the interviews I was asked about my previous experiences and some technical questions related to the interviewer's position. The expected technical level is more than average/what you strictly learn in school.
