Forget Uber driver, what about a code monkey at some YC startup? I've seen the cable show "Undercover Boss" a handful of times and they manage to sneak in company founders with some minimal, reasonable makeup techniques.
Imagine pg entering some RoR shop (or better, Clojure) and getting his code reviewed by a CTO who's a few years out of college.
Do you actually work at a RoR or Clojure shop, or are you speaking from "cable show watching experience" ? Having worked at a number of such places in the Valley, the number of times I've been told that I can't go home or to lunch or whatever until such-and-such a thing is done has been zero.
Now, a finance startup in New York where the stack is Java and .NET? Absolutely.
I meant it would be funny more from a technical perspective regarding his history with Lisp and as something of a programming luminary, other commenters appear to be talking more about brutal work schedules.
