All you need to go through these technical interviews. Different systems require different designs. The payment processor does not have the same reliability requirements as the chat app. The social network does not have the same data model as currency exchange. It is very important that you are exposed to many types of systems in order to be fully prepared.

Our carefully selected design questions cover a wide range of systems, allowing you to participate in interviews with the experience of solving any problems. The practice makes perfect. Intellectual practice makes it even more perfect.
