I discovered the position on Craigslist. It was advertised as iOS or Android. They responded about three days later and scheduled a phone interview for about a week later.

During the phone interview, I learned that they were specifically looking for an Android developer, but were open to hiring an iOS developer as well.

The initial phone interview included many technical questions, although it was conducted by a non-technical person. Passing this interview would have led to an interview with the hiring manager, but that did not happen.

There were many technical questions related to binary searches, binary numbers, and more. These were typical computer science questions.
