0) time doing the project is tracked, sometimes via the expectation that you commit to the git repository from start to finish. dinging you for "points" for going over the time allotment
and that the other candidates are:
1) doing way extra things that took way more than 6 hours
2) are not doing those extra things from scratch because they've been playing this game for a while
and that
3) the company still has inaccurate ideas of what a candidate should be expected to present in the 6 hours
4) is judging you on completely random things that they did not mention. "you didn't use this design pattern" "we don't like MVVP anymore, we're back on MVP. here's this other acronym."
waste of time
