Which is the reason they could be completely different from brainteasers, but are the same in the form used in interviews. People are very, very bad at evaluating on the spot if some "solution with thought-process" which differs from their own is actually completely valid, usually it is: "Nope, that's not how you do it.

You'd have to capture the answer and then study it later, possibly multiple times to overcome any: "Hm, this doesn't sound right, why didn't he think of x, y and z"-feeling and understand that x, y and z are just your bias, not some kind of "correct" part of every answer. I've never seen that happening.
