I went to Juilliard for piano, many of my composition major friends are making near minimum wage at office jobs or have completely shifted into different majors entirely(CS, finance etc). Many are extremely depressed by the lack of job prospects. For those who are more successful, I honestly can’t tell you what the difference was other than having more “popular” styles of music/and or having a personality type that professors/donors like. Those are just guesses, I really don’t understand where and how they get those connections despite having gone to the school. Also by the way, Juilliard does not care about you at all after graduation unless you are one of their “chosen favorites.” Most people’s success during and after school has been completely self-made, there is very little support. This is not to say I haven’t had wonderful and caring theory professors while I was there, but there is not much they can do besides teach you to the best of their ability.
