There were 2 rounds, increasingly harder. my first interviewer was great, the other two were slightly rude. I would still apply again. Ground all your responses on first-principles. There is also a preliminary recruiter call.

HR Call was smooth, mostly logistical and typical behavioral about company. It wasn't hard to get a call scheduled and the process was smooth. Moved onto the first round product sense pretty quickly after the HR screen, and had a pretty intuitive scheduling system.
