Had a phone call with their recruiter and then a Skype video chat with him. After that I had a 30 minute phone call with the hiring manager and then an in-person interview with the hiring manager and one of his senior level managers. Pretty straight forward questions with no crazy curveballs. They really wanted to see how much info I knew about their product, space, and competitors so definitely do a lot of research. It was clear that culture is a huge factor there and they really want passionate people that care about their product.
