Two phone calls, first related to a coding question which tested Python skills - know how to sort things using "key=" i.e. array.sort(key=<something>). Had to finish the task under a strict time constraint. The interviewer was 10 minutes late for a 30 minute phone call. Second interview was a front end time bound challenge. In both interviews, the interviewer did not care to let me ask him any questions, just rushed to hang up as soon as the test was done, which IMO was pretty rude and arrogant. If this was going to be the case and had I known, I wouldn't have researched the background of the company.
