The process started with a recruiter reaching out to me directly on LinkedIn. After an initial talk, they invited me directly to the onsite interview. The onsite consisted of 4 rounds. The first two rounds were mostly focused on data structures, algorithms, and iOS knowledge.

In the first round, I was asked a LeetCode Easy question based on arrays, to recreate some default iOS functionalities (higher-order functions like map, filter, etc.), and some UI-specific questions.

The second round was pretty much on a similar line, but with higher difficulty. I was asked a LeetCode Medium (direct question), debugging questions related to concurrency, multithreading, and memory management, and security practices in iOS applications.

After the first two rounds, the feedback was positive, so I was asked to provide my availability for the third round (system design). This was a pretty standard iOS-based system design round (just focused on client architecture, no backend). I would recommend focusing a lot on local data persistence and caching mechanisms, performance improvements, and standard non-functional requirements (like localization, analytics, monitoring, etc.).

The final round was with the Hiring Manager, where they shared a lot of information about the company, team, and projects. They also jumped into some technical discussions (not just iOS, but also backend and web) and asked about past projects.

Overall, the process was pretty quick and to the point. The interviews were done within a week, and they came back with a positive decision within 3-4 days.
