You've called this one out as bad. Well, it probably is bad. if I invested through this company I'd be upset. But the thing is, its "hunt for keys under lampost, not because I lost them there, but because it's lit up" bad: You know this hire does not make much sense. The other hires, you are letting through because (I believe) you implicitly assume they can learn to do the job, all other bad reasons for hire not withstanding. Why can't he learn them too?
He can take instructions and work, and is physically robust. He survived in a harsh environment (or two). There are admirable qualities which imply he is educable and strong emotionally and phyisically. I wouldn't have hired him or the nepo baby. I wouldn't have put my money into this mobs hands. I didn't. If my superannuation fund did, I hope it returns at least at market norms.
