I was first approached by someone who viewed my profile on LinkedIn. He called me and we talked about my background. I was completely honest and told him I thought of it as more of a hobby, than a job. After all, I had never done professional iOS development before. Once he said I should still apply, I filled out the form on the website, and the next day someone contacted me about coming in for an in-person interview.
The interview was straight forward. Who I am, my background, how I found out about the job, etc. It lasted no more than 20 minutes. The next day I got an email with a description of a code challenge, the iOS version of the NAT. I won't give away what challenge, as that's no fun, but even with my fairly little experience I found it to be easy, and fun. Sure it was difficult, but nothing impossible.
The Monday after I submitted my completed code challenge, I got an email saying they wanted me to come in and discuss it. This didn't surprise me, because I was told that they bring everyone in, good and bad, just for feedback.
I walked into the little room with 3 current employees, and 1 of the developers said, "You're here, and that's a really good thing"
After an hour of a really informal interview, and code review, they said I should hear in a week about whether or not I get an offer.
But I didn't wait a week. I had an email with an offer before I even got home.
