I've hired a lot of remote developers over the years and it has pretty much been a flop 2 / 3rds of the time. I had some reasonably good success with Columbian developers a few years back, but the two most outstanding devs I hired on a remote basis were based out of Utah and Connecticut. I hired one a few months ago from Ukraine who absolutely blew the competition away when it came to the coding test, but then failed to actually put in the work hours when he started the job. Any advice for interviewing / hiring remote devs that don't suck?
