Phone-screened a candidate few days ago and decided not to move ahead. Candidate finds me on LinkedIn and sends me a 2 page email on why I made a mistake with tons of examples and notes on why the candidate is the BEST choice for me. Look, I appreciate the diligence and going out of way, but your opportunity to impress me has passed. This is not a sales role, and if I am not going to give you extra points for your push.
