First, a phone call. If things look good, there will be a 1-day, 5-interviewer session with 1-hour questions. After that, an HR interview. Following that, you'll explore internal opportunities and talk with managers.

Phone screen and multiple rounds of interviews. Behavioral questions and 4 rounds of coding interviews as well. Prepared for multiple months with Leetcode. Make sure you can do Medium-level questions, and check the top 50 lists.

It was three rounds back-to-back of phone interviews. Each one was exactly 45 minutes. The interviewers were very nice. In the last five minutes, I got to ask them a question.
