The stranger who appeared at Kim Kardashian's Beverly Hills mansion Sunday night told police he was convinced he had a LEGIT job interview scheduled with the reality show fam ... TMZ has learned.
TMZ broke the story ... Kim called police late Sunday night when the guy showed up to the home with luggage, requesting to stay in her home.
When cops arrived to the scene, we're told officers explained there was no interview ... and told the man he was not allowed back to the property.
Law enforcement sources tell us ... the man was genuinely convinced someone from KK's camp had set up a real deal interview with him for an opportunity to work on one of their reality shows.
Cops gave the man a trespassing warning ... and then drove him back to a local airport so he could book his flight home.
It's unclear if the man was delusional ... or simply the victim of a cruel prank.
