There's a lot of stuff, but this is the New York Phil we're talking about. They do sometimes play those pieces, you know!

There's nothing on the list that isn't standard rep.
They actually make things a lot easier by specifying what the prelims will consist of, and giving you the option of sending a taped prelim. But every audition involves a significant sacrifice of time and energy. That's why only people who can really envision themselves winning and keeping a job like this should make the effort.
I think some people see the two openings and think "wow, I've got twice as good a chance!" but that's not really the case. If you're going to gun for a job like this, you gotta do the work.
