The process involved one coding round followed by three interview rounds.

The coding round was of medium difficulty.

The first and second interview rounds revolved around OOP, Databases, and Networks. The interviewers were friendly, and it seemed more like a discussion than an interview. Each interviewer asked one question on designing a database for existing, well-known services like Facebook.

The third interview round was quite difficult, with multiple open-ended questions about system design.

Overall, the experience was positive.

Normal forms, Static methods, Network protocols in each layer.
