Interview process was really simplistic. This was my very first contact with a company for an interview and I was told to expect a coding interview over the phone, but it really just consisted of generic questions(tell us about a project you worked on, do you like embedded programming, etc.).

They interviewed us as a group at the same time. So every 10-15 minutes we switch with another interviewer to do a 1:1 interview. There were 3 people who I talked to. They browse your resume and ask questions about what you've done before, such as: tell me what you have done in unit tests, what language are you most comfortable with. So it's all about experience.
