Started with hr interview , then coding challenge , then hiring manager interview and interview with two team members. After coding challenge it look very easy but im sitll not sure what went wrong.

All the processes took 2 months to complete: - Applied online. - Had a screening interview with an HR person; it was a casual discussion. - Engaged in a Technical Interview with the Engineering Manager; it felt more like a knowledge-sharing discussion than a formal interview. - Completed a take-home assignment within a 7-day timeframe; it was a bit challenging. - Underwent a Technical Interview with iOS team members who were very cooperative and well-mannered interviewers.
