I made a similar comment on a different post. Non-determinism does not necessarily mean it cannot reliably reach the correct output (although sometimes it does mean that). Las Vegas algorithims are non-deterministic and 100% accurate. The tradeoff is the time it takes to reach the correct answer is highly variable.

To contextualize this insight in your post and basically just repeat what you are saying: The mistake is not using a non-deterministic system. The mistake could be, in some sense, using it too little. Re-evaluating the same resume 5 times and seeing a high variance in scores is a more useful signal than evaluating it once.
