R3-System design on google meet Q-Workflow management platform: I want to provide a platform to users where they should be able to define a set of tasks as part of a workflow. They should also be able to define the time and frequency when the workflow should run. Features to provide: Tasks could run in parallel or in sequence when successful.  Retry a workflow upon failure. Retry should start from the task which failed. Tasks are able to pass payload to a set of dependent tasks. Scale for 1000 workflows to run at the same time E.g. workflow_interview every 5 mins A -> B -> C -> E               -> D -> F Scope: Database schema Discussion on implementation details I was able to design the system having all the requirements(optional as well) and confirmed for each requirement if the interviewer was satisfied with the solution. I took 1 hour for the complete discussion and implementation. Feedback from panel - I was slow and my xp is not relevant.
