I do not remember exactly the question details, but I had two rounds of problem-solving interviews. First One: A variety of problems discussed on a Linkedlist. Second: Array Sorting and efficiency on list search. There were more platform-related questions asked in the second technical interview ex: Android OS, lifecycles, jetpack & other common questions. Third interview was design system. I was asked to design a feature to update a list in app. In the Engineering Manager interview we talked about my experience in Crypto, Software, prev experience in other fields and the interviewer asked some random questions to evaluate understanding of Computer Networks and Softwares Design paradigms.
