I was referred by someone already working there full-time, and the first part of the process was a 45 minute phone screening. The interviewer had a pretty heavy accent and the phone connection was terrible, lots of static, so it was difficult to understand a lot of what he said, in hindsight I wish I had asked about using Google Hangouts. We were using Google docs so I was able to read his questions at least. There were no behavior questions, just 2 technical questions. After the 2nd question we were at 40 minutes and he said he had 1 question left but we didn't have enough time. I had the chance to ask my own questions for the last few minutes.

1 coding assessment. If you pass, you get to the final round which consists of 4 rounds in one day. 3 technical and one behavioral. The algorithms I had was BFS, Min heaps, and backtracking(parentheses)
