I stopped by the booth at my university's career fair and spoke to an engineer for a bit. He invited me to an interview on campus the next day where he gave me circuits questions. They were pretty standard and basic such as RC equations and transfer functions. After that, I was invited to do a 1 hr presentation to 2 people about a project I did. The presentation was more like a walk through where they asked me questions about the project as I went through the slides. They were all technical questions for the most part about the project, so you better know your project well. However, my project was an analog amplifier and both the interviewers were digital guys, so they didn't really have a lot of hard questions. I passed, and they invited me down to Texas. They paid for the hotel, airplane, etc which was cool. The first night at the hotel you go through a presentation with some of the engineers where you drink a bit and relax. After, you head out to a restaurant. The next morning, I went in for 2 interviews. Each interview was with 3 people. The first interview, they asked me mostly behavioral questions. I feel like they were not satisfied with my responses, considering they let me do most of the talking. The next group of people, kind of treated me like crap. For these interviews, you do your presentation in person that you did over the phone. They kept interrupting me and asking questions that were relevant to the slide that I talked about like 6 slides ago. They asked me technical questions too.

3 rounds. The first was behavioral with very simple technical questions -- what's the offset voltage of an ideal op am, setup & hold time, etc. Second was mostly behavioral Third was behavioral with focus on my resume.
