Three consecutive rounds of technical interviews 1 hour each. - Android - DS & Algo - System Design First, I did ok in the Android round could answer most of the questions except specific bitmap API about sampling size. Second, I did pretty bad and manage to solved 1 easy Leetcode and took all the time to solve the medium one. There was a moment when I struggled to find some Kotlin method since I have worked with many languages. The interviewer also did not know and helped me google it which in the end I received feedback that I lack knowledge of the language which is funny. Third round was system design and I could answer all of the questions.
