I was originally placed through a staffing agency who connected me with the head recruiter. From there I scheduled a phone interview with the head iOS engineer where we discussed iOS concepts such as ARC, class scope, strong vs weak references and other Swift semantics. After completing the phone interview I was asked to come onto an onsite a few days later where I was evaluated in 3 different rounds. My first round was with the head iOS engineer where I was instructed to build a UI to the spec I was provided. The overall scope consisted of a UITableView with JSON data that was to be downloaded from a REST endpoint. The key thing in this task was asynchronously downloading the photos that were then used to populate the table view (know what cell dequeuing is and how it works). My second round was with another engineer where we dove deeper into using constraints to build the spec I was given. My third round was with the VP of engineering where we discussed the culture and what it's like to work at Tophatter.

Phone interview - questions in general about swift and networking Onsite interview - two projects on spot. I completed the onsite project. Just took a little time in date formatting to show it on the screen and was rejected for that :( Overall it was a positive experience. Good people. But it'd be nice to know what exactly they are looking for. Even though I completed the project and They said I was excellent cultural fit , I was still rejected :(
