Re your application to {1} for the role of {2}
Compliment template
Feel the pity for the person on how they put effort into making it look like they had {1}, but ultimately only made everyone laugh.
Joined list of compliments — there is no particular reason so make it known that you just didn’t like the candidate; you’re the god here and the candidate is a small fry
Already found a better candidate
because the company already found an actually decent other candidate (put it in their face how much of a failure they are)
because their skills were extremely poor (make them feel miserable for it)
Education doesn’t suffice
because they are stupid and it showed
Poorly presented themselves in an interview
because the person acted like a socially inept person during the interviews (come up with some fun way how they have embarassed themselves)
Application doesn’t match position (copy-paste?)
because they even didn’t double-check the application they submitted and just sent some copy-paste
Low-effort/AI generated application
because the person clearly submitted a low-effort or an AI-generated application (mock them on it)
because the person is a complete moron (don’t insult the person directly though but mock their actions and skills instead)
Opening not relevant anymore
because the opening had already been closed but nobody cared to update the listing (which isn’t bad because the company thoroughly enjoyed this candidate’s application, which they wouldn’t otherwise receive)
