I received an email two weeks after applying, and HR scheduled a phone interview, which was quick and easy. They then scheduled a second phone interview round with Engineering. I sent them my previous work, but the team didn't understand any of it. They asked many questions unrelated to what I had done. It seems they don't have the right people on their hiring team.

All questions asked were related to your background, but HR didn't understand they were talking to a student who needed to learn a lot.
