The interviewer first asked me about your project experience. Then he started to ask some questions about the sorting and searching algorithm. He just wanted a brief answer like “binary search”. But you can still write programming on a paper or described the concept if you forgot the name. At last he asked me if there is any question for him.

3 rounds of leetcode medium, 2 questions were very easy, the last one was really hard (it was a binary tree question). They asked about space and time complexity. In terms of structures it was straight forward but the question itself was hard
