My question is, how is your company tracking and evaluating performance and participation? I looked at something like creating classrooms in repl.it but the PHP environment does not have any way to add extensions, so setting up Laravel in there won't work. I looked at some other websites like Hackerrank and Coderbyte, but they are focused more on hiring rather than on the job training.
