Home coding challenge building REST apis followed by 1 hour coding challenge implementing Conway's game of life followed by Design interview on , among others, how to poll customer's REST api's given a constraint of how much you can poll weekly. The feedback given by the end of the process was detailed except the feedback on the failed interview which was the last one. It was not entirely clear why the suggested design was not accepted. Another issue was, that the interview was done by a single person and such was solely dependant on one person, which is not recommended when asking open questions such as design questions. It is unfortunate that this was done in such a way at the end of a lengthy and very energy consuming process.
