I applied through an employee referral. The process took two months. There were three rounds:

• First round: LeetCode coding, two problems in 45 minutes.
• Second round: Online assessment for 90 minutes.
• Third round: Four interviews, which were a coding interview with a LeetCode-type problem solving and communication to run the code, an AI-enabled coding interview with an AI agent within CoderPad where you do not run the code and there is no person, an architecture round, and a behavioral interview.
