My dad was first concertmaster of the VSO, and my wife is a pianist. What's interesting is to look at the parallels between auditioning for a position in a prime orchestra and "auditioning" for the position of software engineer/developer.
When you get called to audition, you spend a ton of time preparing at in your "free time".
If you want to apply as a (senior) sw engineer, it makes sense to have an idea about the depth of knowledge and/or the engineering approach of the candidate.
The other side of that coin is many orchestras now do auditions blind - nobody evaluating the artist can see the artist, they can only hear them. The numbers indicate that this eliminates most of the bias orchestras traditionally had for visual attractiveness/friends of the orchestra/white males.
