How someone conducts themselves in response to rejection can affect future opportunities.

It isn't uncommon to be reject a candidate for one job, but approach them about a different job that better fits their skillset. This can happen even year or two down the road if that candidate left a good impression with a senior person who hires people regularly.

Worst case scenario is that not only are you rejected for that job, but are considered not hirable for other positions in the future. Trying to prove someone wrong after they have rejected you for a position indicates that you do not respect their decision, and feel entitled to reconsideration after they already made their choice clear. It's disrespectful.

Keep your dignity, and maybe that job rejection turns into a valuable opportunity down the road.
