if you know a department manager at a supermarket you're more likely to get a job in that store than someone who doesent know anyone there.....
all jobs are like that. its a part of life... changing it is impossible.
That's quite a defeatist attitude to the problem.
Contrary to what you might think, IT IS POSSIBLE to change because some orchestras have proven that it can be done. The best practices (as practiced by some orchestras) for fairness are: 1) screens never come down, 2) no automatic advancement of anyone--NOBODY gets advanced automatically, 3) mandatory audition winner (but probationary period allowed just in case the winner is a douche bag or just had a lucky audition day and to make sure that the winner is indeed the one)
It's not impossible. The orchestras just have to have the moral spine to do these things (as some do).
Also, here's a new suggestion I should add, that no mobile devices (laptops/phones/tablets/etc.) should be in any audition committee member's or proctor's or gopher's possession from the minute the first auditionees check in until the audition is over, so favored candidates can't text their number to sympathetic audition committee members. (Yes, this happens, but it can be prevented. In the old days you just made a certain allowable noise as your signal, so if you really want to cheat, you can still do it the old-fashioned way.)
And we should bring back some practices from the old days:
candidate access to comments sheets and allowing candidates to record themselves for true honest feedback in evaluating their own audition performance.
And here's an idea that is pure fantasy: if there is a "no-hire" the principal or someone in the section comes out and makes the announcement that no one is good enough, and then proceeds to DEMONSTRATE the audition rep ON A BASS (INSTEAD OF JUST TALKING ABOUT IT), to all the candidates who were not good enough and to the conductor and to the rest of the audition committee how someone would have had to sound in order to win the audition. I think that would cut down on the "no-hire" scenarios significantly.
OR, we can just throw in the towel and pick orchestral bassists like grocery store managers pick their stock boys.
