I really don't understand what the point of creating these puzzles and then failing to disclose that you'll reject, out-of-hand, an entire subset based on such hidden criteria. It feels like firms want anyone else, but themselves to train junior|entry-level|new grads or only accept new grads with the requisite level of moxie who have had the luxury of time and money to have trained themselves or been able to establish businesses.

Some people had to work whatever job(s) they could find or had family issues to deal with and go to school at the same time. Are they less qualified because of it?
