PAT - Sound engineering auditions

My D is selected for the skype audition for the PAT - Sound engineering program. Please advise on the format of the audition and what she should prepare. Any tips on what they are looking for, will help.

my D completed the Skype interview today for PAT sound engineering. There were two teachers in a studio. They asked her to pick the favorite item in the portfolio, and then they played the whole track out loud in the studio. They asked the process behind on making a song and how she learned certain terms like pan and how she approached multiple recordings. Later they asked her how did her singing help with my compositions and they also asked why the PAT program. It lasted 20 mins.
