There are 6 rounds in total. The first round was online data structure, followed by system design. Data structure focused mostly on trees and graphs. System design was tough, with a focus on scalability and creating a large enterprise app.

The process included two online assessments (one technical, one workstyle simulator). This was followed by two back-to-back technical interviews for the final round. A few days later, I received the decision via email.

The interview process was long and hard. It included an HR call, a senior manager interview, and then six back-to-back interviews with the team and a "bar raiser." The final round was very hard and seemed to be unnecessarily so.
