First round was a 3 or 4 - question HackerRank which I passed despite not having made it through all the questions! The second round was a 30-min technical phone interview along with Code Pair. I had seen all the 3 coding questions before but I wasn’t fast enough in responding since Python is not my first scripting language, so that might have been the potential reason of my rejection. The last part of the phone interview was a coin flip probabilty question which was really interesting but I gave a somewhat correct response!
