Design a distributed task scheduler

Task was to design one of their internal systems based on the given requirements. In the end, interviewer said my design matches their design with only a few tech stack changes (I used AWS services while they use opensource tech). I don't remember the details but the question asked took me some time to understand the concepts and terminology they use internally. Once I understood the question, I realized it was similar to something my old team had tackled but for a different problem space. It was a type of distributed task scheduling problem.
