I applied through another source. The process took three weeks.

• Attend the hackathon after being shortlisted from the HackerEarth Challenge.
• There is a brief talk about the company and functional programming by the CEO.
• You are given a problem statement, and once you come up with an optimal logic, you are asked to write code for the same. We were given a problem on graph ancestors and children locking.
• Then you are asked to write code.
• There will be a F2F interview happening in parallel.

The F2F interview topics varied from distributed systems, system design, network protocols, OS, hashing, and indexes.
