It's a rookie mistake at the informal interview: not wearing clothes.
A naked numbskull -- apparently on methamphetamine -- was caught on tape asking for a job at a welding shop on Saturday and then trying to fight off arresting officers in Sacramento, CBS 13 reported.
In a video captured by shop workers, Jose Ayala, 36, can be seen standing and then squatting in broad daylight as employees call the cops.
"I turn around and I'm like, whoa!" shop owner Chris Johnson told the station. "He said something about [how] he was looking for work, and he was good with his hands. I didn't know why a naked dude would be in my shop."
For most of the clip, Ayala stares off into space and scratches his head, either squatting or walking around aimlessly just outside the shop. But when officers arrive he becomes irate, trying to fight them off and even latching on to a female cop's hair before Johnson and his brother help pry the nude man off of her.
"This guy could have got a hold of either one of their pieces and it was dangerous," Johnson told ABC News 10.
The station reports that Ayala and the officer sustained minor scratches during the melee. Ayala was taken to the hospital for a checkup before cops threw him in jail on charges of officer assault and indecent exposure.
