This reminds me of the litmus test my father had in his small business years ago. Every new employee, no matter where they worked, had the same first task: clean the bathroom. Lots of people never made it through the first day. I guess he figured that the best way to have employees who would "wash the dishes when nobody else will" is to only hire those who would.
Maybe it's just my millenial entitlement, but that strikes me as a bad strategy. Unless the business was a cleaning or maintenance company, cleaning the bathroom seems far removed from anything relevant to my work and is in essence busywork. Questions that immediately spring into mind: is this some weird attempt at saving money by having employees do both their job and cleaning? Is this supposed to be some hazing rit…
This had nothing to do with relevance, busywork, hazing, saving money, or evaluating talent.
It had a single purpose: to determine willingness to do an undesirable job. That's it. Which, interestingly, is just as important in a software start-up as it was in my father's business so many years ago.
