I interviewed for an iOS Developer position at Robinhood in the United States. The process was well structured and focused on both practical iOS knowledge and general engineering fundamentals. The interviewers were professional and gave clear explanations of each stage. The technical rounds covered Swift, iOS architecture, concurrency, networking, testing, and problem-solving. The coding portion required writing clean, correct code while explaining trade-offs. There was also discussion around mobile system design, such as data loading, caching, error handling, performance, and how to structure an app feature for long-term maintainability.
