I applied through a college or university. The process took two weeks.

First was a coding test: Around 180 students took it. There were three questions on N-ary trees and graphs. Sixty-five students were shortlisted for the next process. This process had two sections:

• Hackathon or Learnathon divided into two parts.
• Technical Interview and HR round.

I would suggest focusing on trees, graphs, multithreading, and system design.
