4 rounds of interview, 1st round is a general HR round, 2nd one was backend with 2 leet code style questions, the first one is pretty basic and the second one was a twist on 2Sum problem. This was followed by a system design question which was to design a logging system. The second round was front end question answer style interview that covered topics of typescript, security and architecture. The last round was in person which was a system design round to design a notification distribution system. Overall it was very concise and enjoyable
