The one drawback to audition interviews is that they can be influenced by the same kinds of social biases of any interview. "blind" auditions of this type are very difficult, and somewhat impractical, to achieve. They can also be a problem if the job they are interviewing for doesn't have a performative aspect similar to the performance found in the interview. For example, if the only presentation they are ever going to make is in the interview, it's not obvious if a "good" performance indicates fitness for the position.
