First, there is a round of coding where you are expected to solve two questions (LeetCode easy-medium).

Then, there is the final round, consisting of four interviews:

• One coding interview
• Another coding interview
• One behavioral interview
• One system design interview

The coding interviews are similar to the first round.

Design Ticketmaster focusing on two areas:

• How to hold tickets before payment so users can enter their payment info with a guarantee that they will get the ticket upon payment.
• How to implement functionality such that users will see a waiting page if there are no tickets currently available. Upon tickets becoming available (by users who were holding tickets and ended up not paying), users would get redirected to the ticket buying page.
