I applied and heard from a recruiter a few weeks later. He passed along my information to the software team. I had a phone screen with 2 engineers and a manager. They asked a bunch of object oriented questions which, as an EE, I couldn't answer. They decided to pass on me, but suggested I interview with the hardware team. I had a phone screen a few days later with a hardware manager who asked me very in-depth questions about a project I worked on. A day later, I got a call from HR saying they wanted to fly me down for an interview. I went down about a month and a half later (due to my busy schedule) and interviewed with a team of 4 (2 hardware engineers, 1 software engineer, and a manager). The whole day took about 6 hours, with an informal lunch break in the middle. I presented on previous projects/jobs and then interviewed with each one separately for 30-45 minutes each. They asked very tough questions. I also talked with HR for a while and got a tour of the facility. I got a phone call with an offer about a week later in which they gave me plenty of time to decide. The whole time, I was incredibly impressed with HR. They were very quick to respond and gave me all of the necessary information.
