Unfortunately in a lot of the top programs you will find some experiences of “cut throat” behaviors. It won’t be always and it won’t be everyone, but the study of this very personal art will always include egos- from both students AND faculty.
Many BA MT or BA Theatre programs will be much less “competitive” once in the school, but again, the problem isn’t necessarily unavoidable. Definitely try to reach out to alum of programs you’re considering and try to get a sense of reality there.
