A recruiter got in touch with me and asked if I'd consider applying. I said sure. After a preliminary phone call/talk the recruiter said they'd set up a technical interview with someone on the engineering team. I never heard back from them, even after following up several times.

I applied online and was invited to come interview in person in the Redwood City office. I was interviewed by 3-4 members of the Engineering team, including the team lead. They asked mostly technical questions, about SQL, algorithms, Ruby/Rails and TDD. After the interview, they gave me an assignment to complete over the weekend.
