Had 2 Interviews with the company over the course of a few weeks. They weren't super timely about getting back with me but the interviewers were very friendly and helpful. Their HR isn't exactly very fun to deal with though and they lowballed me.

I had a ~30 minute phone screen with a mid-level engineer in the same department, and was invited to come in-person for a several hour interview. I rotated between HR and several levels of engineers including a dept head, a couple senior engineers, and a prospective team member. I wasn't given many direct knowledge questions, but they clearly steered conversation to see if I knew what I was talking about.
