My frustrations lie in the screening process, and the general no-hire problems. I have put orchestras on my personal list of places not to audition when being asked to provide recordings more than 3 times in a row. At that point, it doesn't seem worth it to me, but I'm also in a place in my life where I'm comfortable picking and choosing where I audition (and I find no problem with that now; I used to be the kind to throw myself at everything, but my mental health is worth more than prepping every audition under the sun. That's just ME though).
As for no-hires...is it really that difficult to award the finalists a trial? I'm asking from an admin point of view as well, if it's just too expensive to provide trials for 3 people or so. We know the audition process is nothing like sitting in the chair itself, you may as well give people the opportunity of a trial before declaring a no hire. Give them the opportunity to prove if they can play in the chair/mesh well with the orchestra. If no one steps up to the plate, cool, at least you've done the "research" you know?
Just my two cents.
