Total of 5 round, 1 screening round consist of coding and OS question, 4 techs round consist of coding, OS, design, architecture, cultural fit. I was referred by a friend, each round was mix of coding and systems question and question were easy to medium category, for coding question they don't actually need you to write an executable code but rather more interested in your approach and thinking. They are also interested in how deep your knowledge is in fundamentals

They asked to talk about some projects I worked on and then also asked two leetcode questions. I answered both questions correctly, although the second one I answered more slowly and the code was not organized but the solution was correct.
