I was asked this question in HLD round for Zepto for SDE3:\n\nDesign a health consultation app\n\n* The user can login in the app\n* The user can book an appointment for a doctor\n* A doctor will be assigned after from a pool of doctors available.\n* The assignment is at runtime, that is it is assigned right after an appointment is created\n* Once a doctor is assigned. He cannot be assigned to anyone else till the appointment is closed/canceled\n* The user and doctor can converse/meet using chat or video.\n* The doctor can generate prescriptions.\n* The doctor can close the appointment, or refer someone else, or appoint himself for a later date.\n\n*Please share some thoughts how this can be solved in comments!*\n\n*Can\'t find a similar system design solution online so if anyone knows please post in comments!*\nThanks in advance!
