I applied online. The process took 3 weeks.

There were 5 stages:

• An initial task that had basic SQL and DSA questions.
• A 15-minute call with an HR representative, which was very smooth. She was nice and patient.
• A technical call with a senior engineer who provided some Java code to review and correct. Familiarity with good coding practices, as well as basic design patterns and OOP concepts, would be helpful in this context.
• A systems design round where you just need a good understanding of how to design and scale enterprise-scale backend systems, and understand the tradeoffs and critical points.
• A chat with a C-level engineer who was a pretty chilled guy and a very good conversationist.

Generally, there were 5 long rounds, but it was an okay process.
