I applied through college or university. The process took one week.

• Round 1: A DSA round on HackerRank. I was given three questions to solve in 90 minutes. I solved them and, after 45 minutes, was selected for the second round.
• Round 2: It was a machine coding round. I was asked to design Ola, and I implemented half of it.

There was a hard DSA round: for every edge in the given array, return if it was present in the shortest path between the node a and b or not. The machine coding round was to write code for an Ola design.
