I think LC is used mostly as a metric of how much tolerance you have for BS and unpaid work: If you are willing to put unpaid time to prepare for something with realistically zero relevance with the day-to-day duties of the position, then you are ripe enough to be squeezed out.
Cynical, but correct. I've long maintained that these trials, much like those we encounter in the school system, are only partially meant to test aptitude. Perhaps more importantly, they measure submissive compliance.
