There were 4 rounds of interviews. All the rounds were coding and some general questions. One interviewer asked me how to put 2-3 divs side by side. is that what you ask a Principal Engg? 2nd interviewer asked, reverse string. 3rd interviewer asked LRU interface, when I gave him the interface he said he needed generic. No one asked me architectural/design questions or system design questions or algorithmic questions. Not good interview process and questions

NDA. In a generic way I can tell there were medium/slightly hard LeetCode level questions. Anyone who is familiar with medium level questions should be able to pull it off. Design questions are however very subjective. Study as hard as you can and try to understand the request before jumping on any design. Ask as many questions you need to have the best approach. Also time yourself so you don't lose your window.
