My process started with a quick HR intro, then I went into a technical round focused on Swift and SwiftUI. That section felt more like random questions than a structured problem, and it left me trying to piece together what level of depth they expected.
I started with a short HR screening call, about 10–15 minutes, and then moved quickly into a more focused interview with a hiring manager and another engineer. The conversation stayed pretty resume-based—there weren’t many behavioral questions, and it felt like they were trying to map my background to the role rather than test specific interpersonal stories.
