Had the standard phone HR interview, phone interview with a technical lead, and then a 5 hour on-site interview with members across different departments. They paid for my transportation in terms of flights and getting onsite. They also asked a lot of engineering drawing questions which I didn’t expect since it wasn’t part of the initial technical interview or part of the job description. I didn’t get up getting an offer, and they didn’t follow up with either of my emails or send an outright rejection which was kind of annoying.
