I applied through an employee referral. The process took five weeks.

It started with a HackerRank OA, which was relatively easy. There was a phone screen about two days later, which took about half an hour. There were no surprises here, and it featured pretty standard questions. About two weeks later, I was invited to a technical interview. It was one hour long and similar in difficulty to the HackerRank.

The final round was three hours long and split into three parts:

• Two technical questions, both similar in difficulty to the prior ones.
• One system design question.
