I applied online. The process took two weeks.

It was a standard process as outlined on their website. I do want to provide some feedback for their pair programming interview, as it seems like most candidates chose the take-home project instead. After making the selection, they will send the base code with a README file to you, which is fair since you don't need to ramp up on the code during the interview. I also like that they include a README file along with the code stating what they are looking for in the pair programming session. Unfortunately, this is probably the most misleading document in the world. It is clearly stated in their README file that "This is not a memory test. We do not expect you to recall every DateFormatter or UITableView API; looking those things up on the web, reading docs, or asking the interviewer is totally acceptable." And when I was rejected, I got negative feedback that there were "Signs that they're not completely comfortable with iOS frameworks (e.g., how to format dates...)" because I asked about the DateFormatter and UITableView API, which clearly contradicts what they stated in the README.

Every iOS engineer knows that Xcode has auto-complete, so given time we can definitely get the exact API they are looking for. Because of this statement in their file, I opted to ask my interviewer rather than looking for it using Xcode, but apparently this is not what they want. It is funny how this turns out. So, a note to future candidates who choose to do pair programming: you absolutely need to memorize every DateFormatter or UITableView API if you don't want to end up like me. Do not ask your interviewer for the APIs. Oh yeah, probably just don't believe what they are looking for in their README doc.
