I'm of the very strong opinion that these novelty questions are basically ego stroking on the part of interviewers. There is absolutely NO scientific or statistical reason to expect they measure any real world performance attributes, of have any predictive behavior whatsoever.

My concern, if asked a bunch of these, would be that this is an organization governed too much by woo and flimflam.

Over the years various aptitude tests, honesty tests, character tests have come into fashion and eventually faded. They tended to work on the theory that 'clever' questions, or looking at what colors they liked could elicit real information about the applicant. Typically the only 'scientific' testing of these was alleged evaluations clothed in proprietary secrecy by the vendors of the tests. Typically when and if they were exposed to REAL scientific testing the spectacular results somehow disappeared.
