See here for the previous interview: https://www.1point3acres.com/bbs/thread-1146238-1-1.html This round consisted of one coding question and one Subject Design question. The coding question was about a course scheduler. An additional requirement was to always choose the course with the smallest ID from the available courses. The solution used topological sorting and a priority queue. The Subject Design question was about designing a Matchmaking Service for Multiplayer Games. I recommend searching for this question and interview points on hellointerview. Before the interview, I prepared three frequently asked questions: Design a Delayed Payment Scheduler Service, Design a Like/Unlike Feature, and Design a To-Do List App With Multi-User Collaboration. I ran out of time and didn't prepare for this one. Unexpectedly, it was asked. I completely improvised. I thought I would fail, but I passed. Next, I'll be interviewing with the Hiring Manager and the Director. If anyone has experience with this, please share.
