I have a friend who's hired a Russian programmer as a mentor on upwork.com. I have in the past mentored someone learning programming, but he was and still is my best friend since high school, and now he works as a programmer. It mostly consisted of insisting he do his assignments by himself and refusing to share what I've got.
