I don’t mind code walk-through, but that can be over Skype or TFS. Mentoring I would rather do to groups in a classroom kind of format, I have years of experience doing that, careers and advanced English here in Vietnam.
When I code I need to be alone, preferably wearing headphones playing something either solemn like Palestrina or dark and brooding like Steve Roach, lights out, darkmode in the editor. When I get into flow it’s a joyous feeling.
Pair programming feels like being buried alive.
