Not programming, but in the same vein, A Trek Bicycle store manager asked me in an interview if I would be willing to work a trial shift the next day building bicycles. Unpaid, of course. Just to see if I was a good fit.
Of course, since I was used to building 50 a day, I would have gotten all of them done in a single shift whereas they were needing to call in stores from surrounding areas to come help in a few days.
I laughed and said if they needed help tomorrow I would be happy to work for my usual fee of $20/bike.
Oddly, I did not get the job
Not once in my enlistment, such as it was, did I question what was in the pants of fellow service members.
Nor did I question their capabilities when they were needed.
Because I'm not an insecure idiot with the maturity of a child.
