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.
