Oh dear, it sounds dreadfully gimmicky like those magazine articles "My life in 9 objects".
It is interesting to see fads and fashions in interview techniques, in-tray exercises, PowerPoint presentations, sample lessons (performances) .

Forgive my cynicism but DD used to be a director of an international financial recruitment company and being asked for "feedback" after her interview at Birmingham University for her PGDipEd course when she decided to retrain, was also asked for her "professional" assessment of the interview itself.
She was tactful.
