From a comment on Hacker News:
I think this is missing a critical step - the candidate needs a way to see the result. I don't necessarily trust a random recruiter to be honest when they tell me "Oh yeah 100% it said we're compatible." Could you make a link that the candidate can use to verify the outcome? Alternatively, when I the candidate visit the link that I sent the recruiter (after they submit) it could just tell me (and them, if they revisit) the result.
I agreed, writing:
I think this makes sense. My initial assumption was that the recruiter has no incentives to mislead the candidate, but now I can think of some scenarios where there are incentives to do so.
Beyond that, even if the candidate kinda trusts the recruiter, I think it would be psychologically comfortable for the candidate to have some "official" confirmation.
