The company contacted me through AngelList.com. First 30min phone screening we talked about what company goals are and what my career goals are. Second interview was on-site, I went to company's office in San Francisco. 2 of the 3 engineers I interviewed were easy going and asked me general questions about my previous programming experience. Last engineer was on the team that I was going to join so his questions were more technical and deep. I did well on the interview the followed up with offer in a week.
