Got an interview through an internal reference. The first round was an online code test, which was 2 questions in around 30 minutes. The second round was a phone screen, where I was asked 3 algorithm questions. The third round was another phone screen which was 2 algorithm questions. Both phone screens were 45 minutes. I passed both phone screens and was called for an onsite interview, which is 4 interviews with 4 different people. Each one is 45 minutes and the interviewer asks 1-2 algorithm questions.
