Began with a standard phone screen. Second interview were personality and technical assessments with HR and an engineer, respectively. Coding languages were targeted toward web development, not embedded development. Third interview involved speaking with 3 different employees including potential manager.

I had an on-campus interview with multiple software engineers and an engineering manager. They asked me some questions on embedded C (generic ones you can look up, it is probably what they did) and RTOS concepts. They invited me to an on-site interview a few weeks later. I interviewed with two engineering teams who asked me about my projects and general software engineering concepts. They also asked behavioral questions like how I dealing with conflict and taking risks in the workplace. Someone called me back after about two months saying I will get a call from a manager about an offer, but I never heard back from them again.
