The advanced UPRT course is a requirement prior to the first multi pilot type rating, not necessarily prior to being recruited by an airline.
If it wanted to, an airline could recruit pilots without the advanced UPRT and then send them on an advanced UPRT course before the type rating course.
This would enable the airline to evaluate and select the the on aircraft UPRT providers to assure standardization of UPRT between aircraft and simulator.
