45 min interview with software engineering manager, 1/2 behavioral questions, 1/2 leetcode interview where I was asked about dfs pre-order traversal both recursive and iterative. Then they did 2 purely technical interviews with team members. One was a object-oriented programming question, designing a parking garage structure. The interviewer added layers and questions to the problems step by step. The other interview was a more whiteboard system design question, about designing a payment system, the interviewer gave me zero direction. I aced the leetcode and object oriented programming interviews but I did terrible on the system design question which led to the no offer. This is the only company I've ever heard of that asks junior devs system design questions. This is objectively a stupid way to interview junior devs. However, if you are desperate for a job at what appears to be a dysfunctional company, just study and memorize the system design for a payments app, it's the only system design question they seem to ask after looking at the other interview anecdotes.
