Passed the phone screening easily. The next phase involved a live coding challenge. According to the interviewers, after the coding challenge, there would be a virtual onsite which would involve about 4 more interviews. The coding challenge required a surprising amount of code given the time limit (75 minutes, ~130 lines of code). Some of the requirements will not be told to you until after you complete a basic program, but these could easily be mentioned at the beginning to streamline the process. I spent about an hour of the time making sure the program worked very well, with exception handling, threading, and clean design. I took my time because there was no indication a "part two" was coming. By the time I got it, there wasn't enough time to fully finish it. It felt like a waste of time because of this. It would have been straightforward to finish if I knew a "part two" was to be expected, but I spent so much time making my solution high quality because I was under the impression there was only one problem to solve. Seems they were more interested in coding as fast as possible and seeing how the interviewee handles a "gotcha", instead of focusing on quality and performance of code.
