Very long case study in a short amount of time. Requiring presentations, data analysis and a P&L. A suggested 5 hours in 72 hours would not put a dent in the required work. Exceptionally vague brief. If you spend the time needed to complete the task you can be critised for not being efficient. If you put in the recommended 5 hours, you wouldn't have gone the extra mile. The damned if you do, damned if you don't. The right answer to what you are meant to do here would depend on the whims of the assessor. When they could have simply done a timed 1 hour case study for the top candidates to not waste everyone's time. And be of a sensible scope. Poor experience with HR. Asked me to do many hours of unpaid work, then rearranged and cancelled meetings, not giving me a fair chance. Probably my worst job application experience.
