First is 30 min interview with HR, she was kind and polite, didn't have any problems. She asked some iOS related basic questions like Struct/Classes etc. Second interview was a Leetcode task for 1 hour. (Algorithmic task) No other questions about Swift or iOS were asked, just a brief introduction and then you should work on it with a shared screen. I didn't know it in advance and failed it, so I post this for future candidates so people could prepare.

Interviews with the manager, other software engineers within the team, product manager, and VP of product. 3 rounds in total. Also was given a medium-difficulty take-home assignment that took about 6 hours to complete.
