The interview process takes about 2 weeks. First, I got an OA problem, which you can use your own editor and does not provide any test cases. Then, after two days, I got a reply from HR and scheduled a phone interview. The phone interview was hard. The interviewer asked one algorithm question and one design question. Then, I got replied on the next day morning saying I can proceed to a remote onsite interview. The HR called me to tell what the onsite interview would be and asked some behavioral questions. The onsite interview was very hard. In the first round, I was asked one algo question and one design problem by an engineer. Then, I was given 80 minutes to complete a problem on my own. Next, I was asked to explain my code and answered some followup questions to another engineer at Asana. Then, he asked me one algo question and another design question. I got replied the next day saying I passed the interview. The interview process is really fast, and the questions are hard.
