Coding interviews don't ignore any facts - they are simply often the best signal/time tool available. Many people do not have time to root around in your personal repositories or wait for you to commit pull requests. They have a pipeline of people they need to screen, and you can't wait on everyone in a pool of candidates to take their sweet time before deciding on a winner. Technical screens are synchronous and relatively well understood. If they are not the literally BEST choice of time for figuring out if someone is a good developer, they are at least a very defensible choice.
