Brooklyn, 15, spent four days at the filmmaker's office in London, reported Daily Mirror.
Brooklyn was dressed casually, carrying a backpack, but did have notepad in hand.
"After arriving at the director's Grade I listed home, he was then walked to the office, where he was spent five hours before being picked up by a member of the Beckham's housekeeping staff," an onlooker said.
The teen's work experience news comes after recent reports that he had found a job in a coffee shop. He had been doing weekend shifts at his local cafe, where he was apparently paid 2.68 pounds an hour.
