I applied through a college or university. There are six rounds, where mostly everyone will be wiped out in the first round, and the second will be easy if you guys prepare previous year questions. For the third round, they have it like six hours of coding for two days, and you need to implement and get the best complexities; if not, you will be rejected.

The questions were Converging Maze: nearest meeting cell, Converging Maze: largest sum cycle, and Max Weight Node.
