I made it to the 2nd part of the interview and I'm sharing because I have no clue what this agency is going for. You do a mock session with a woman who wants to lose weight but doesnt want to give up eating at restaurants or cook. So I figured I'd meet her halfway and have her eat healthy foods at restaurants. I got her to agree. Figured we take it one step at a time since this woman was so against any change. I get that the company wants to see how you would react but I built empathy with her, build rapport and made sure she took a small step towards a healthier her. But I didnt get the position. So I'm sharing for future candidates out there. Maybe my experience can help you. Good luck!
