I started with a questionnaire that I think acted as a phone screen. Then I had a second 45 minute interview and then finally an interview loop with 4 different people. 3 with behavioral questions and a coding questions and then the last was system design.

First Screening call, then initial interview with an engineer (1 hour) and then final interview with four 1 hour rounds back to back with different engineers. For each round its the same, you'll be asked one behavioral question and one coding (LC style) question.
