I’m often asked to complete a case study as part of the hiring practice. But more than that, even if I’m not asked, it feels expected for me to proactively craft a deck of materials proving my understanding of the rule and how I would contribute to that particular project. This work generally takes about one week, part or full time. I can see value in the practice if the hiring company is really serious about the candidate, but personally I’ve lost a LOT of time doing this kind of personalized work only to be passed over with no feedback or explanation. If required by the hiring company, I think this work should be paid.
