After the initial call with an HR, I got a take home test on some kind of a platform like Leetcode, but with a more real tech problems to solve. It wasn’t very hard so I quickly solved all the tasks and submitted the whole thing. Only one thing to mention, the platform tracks whenever you leave the page when you switch tabs. After the task I got opportunity to speak with one of their senior developers. They were pretty impressed about how quick I submitted the solutions but after some regular questions started to ask some odd things to me that were not related to iOS development or other behavioural skills.
