Horrible! During my "Live" (why quoted - below) Coding Challenge, while working on the second task, I had to fix THEIR own issues with the testing system: - their parser of the input data was NOT working, thus I had to replace it's logic with the hardcoded test data. - the pre-defined arguments for the function you're expected to write were not enough to solve the issue (specifically, the only argument provided to the function-to-be-implemented was of type "int []". It's impossible to figure out the size of a C-array in C++ without explicitly providing it e.g. as a second argument. Or, you should use std::vector<int> instead) Finally, when I submitted my second task to the system I got "timeout" response, even though there were still some seconds left and I spent last minutes writing comments for them to fix their(!) issues. Another weird thing was that in their email it's stated that the interview would be "held over a video conference. During the interview, you will be asked to share your screen and webcam", but in fact no one contacted me at all, I solved the challenge on my own, without any web-conference/web-cam/talking/chatting. The only "live" element was the timer, preventing me from spending more than half an hour on this stupid platform.
