The first thing I would consider is the unprofessional approach. Maybe read the parts of the prompt when she was "wearing a sleeveless shirt, smacking her gum."
Would you do this while walking into a job interview? Probably not.
Then, keeping those in mind, try to consider some ways to revise or rethink her approach. How would she come to a job interview next time? Maybe a better wardrobe or to cut off that gum.
Lastly, imagine you were talking to a person. All you have to do is imagine that conversation and talk through that pencil (or keyboard). How would you give advice and suggestions to someone who just tanked an interview?
Hope this helps!
