There seem to be a whole lot of platforms out there to do collaborative coding interview online. Many seem to look essentially the same: left side an editor, right side a terminal, and a green 'run' button to build (if necessary) and execute. Supporting audio and video is a bug plus. But I haven't found any that allow you to include things like supporting code or datafiles. I want to give candidates a chance to show how they work in a more realistic environment rather than transferring classic whiteboard problems on a new platform. Part of that, for me, involves providing some support code that they may or may not have the source code for.
Any suggestions welcomed!
