I had this interview a few years ago. I recall being observed in a small group discussing a scenario from a card and being asked what we would do. I don’t recall all the details, they just want to know if you can follow instructions and avoid doing anything dangerous. Listen carefully to the instructions given to the imaginary and don’t allow others to influence you if they decide that they are following the wrong path in the scenario, just state what you believe is true of the scenario. Don’t ever argue with them just state your case calmly and with enough confidence, the assessor will hear you and it’s them giving the job not others in your group. Do not wear jeans ! Wear profession business dress, like the assistants do in the store. Good luck 😉
