> Your candidates show that after learning how to solve a problem

The way I read it, they’ve shown they can learn the solution to a problem.

It’s like asking ”what’s 43 × 57?”, getting “2451” as a reply and, from there, assuming they’ll be able to calculate ”42 × 58” or “41 × 59”, too. If they memorized just “43 × 57 = 4251”, that conclusion may be (and likely is; most people who know how to multiply won’t memorize such products) incorrect.
