Design a Dating App (Tinder) Interview Question
Outline how you would create a tinder style dating app. The functional requirements are the ability to create user profiles, location based recommendations as well as the ability for a user to change their location (passport mode), preference settings, and matching algorithms. You can ignore chat functionality because that is often covered in other system design problems. The nonfunctional requirements are the ability for the application to scale to a large number of users as well as spikes in usage at different times. Availability and low latency are also a concern.
