But seriously for an all-around (not just a new bike assembler), I'd test them on
Servicing/adjusting suspension forks (a couple different brands and types)
Checking frame alignment
Servicing disc brakes
Optimising canti brakes
Install a threaded headset and fork
True a wheel with a bad hop
Build a rear road race wheel with an assymetric rim- calculate spoke length, (radial non-drive side?) and adjust for proper tension
replace bearings on cone/race hub
... and dealing politely with 15 year old customers with lots of questions all at the same time
