Basic STAR method phone interview, with some technical undergrad-level engineering questions thrown in. The engineering manager for the engineering team I applied to had first emailed me with a standard list of questions to garner eligibility requirements and if I was a good fit for the team. Some questions on the question form were the standard "Why do you want to work for____?". The next step was a phone interview. I performed well in the phone interview but was not chosen over someone else with former military experience.
