Initial very brief phone screen with a recruiter. We talked a little bit about my interests and why I wanted to work for Blue. The next day, he set me up for a phone interview with a senior engineer at the company. We mostly talked about the design project I worked on for my Formula SAE team. It was mostly a technical discussion about some of the design decisions I made for the project. I felt okay but not amazing about the interview, and was reasonably surprised when my recruiter called the next day asking if I wanted to head up to Kent, WA for an on-site interview.
They flew me up a few weeks later. When I got there, I got a tour of the plant (which is amazing, by the way!), after which I gave a presentation to about 6 engineers. The presentation had to last about 30 minutes, though they gave me an hour time slot so they could ask questions. I had to talk about my background, interests, technical skills, and give a brief rundown of my resume in the first part of the presentation. In the second part, I had to talk about a technical project I had worked on.
After the presentation, I had a one-on-one interview with each of the engineers who sat in on my presentation. They mostly asked more questions about my technical project, as well as a few other questions which I've highlighted below. The hardest questions I got were questions about optimizing a wing spar (ie cantilevered beam) for increasing natural frequency and for strength. At some point during the day, a potential supervisor and potential coworkers took me out to lunch nearby. Got to the plant at around 9am, left at about 4pm.
About a week later, I got call saying that they were going to pass on me. I was surprised, because I thought I did very well. They were looking for someone with more FEA and manufacturing experience than me at the end of the day. I think part of their decision was based on a few philosophical differences that I had with the team on the way I executed certain parts of my technical project. I probably would have benefited by being a little less stubborn and agreeing with them a little more, and telling them what they wanted to hear.
