There were a total of three rounds.

They provided one design problem to solve before the interview.

• The first round was a review of the design problem I was given.
• The second round focused on coding skills.
• The third round covered architecture design and a puzzle.

A fourth round, with the hiring manager, was scheduled but was moved to a phone call due to time constraints. This call was to happen after collecting feedback from the interviewers. It never occurred, and no feedback was provided, even after I inquired through HR.
