I am currently in the interview process; Went through the first coding round. There were three problems and they were fairly easy. The time limit was 2 hours but it only took half the time to finish all three problems. The next round is a one sided video interview involving math questions. You have to walk them through your thought process while solving the questions and say the answer out loud in english. It is a math based round involving 7 multiple choice questions and you have 5 minutes for each.
