Internet connectivity means they only need one person on duty at the central office. If this weren't immigration law enforcement, they could even outsource it. :-)
I suppose they could hand out iPads while we're on line and have us complete HackerRank exams. So if someone is a plumber, would they provide a set of pipes to connect? What about a heart surgeon? That might get messy...
That's a good point. They could have an office with people on duty that remote-interviews everyone about all different kinds of jobs. Not saying it'd work well (no idea if it would), but I do think it'd work (a lot?) better than the scenario I first imagined.
