Yes but you were probably just doing tours walking around (while the factory owners rushed to make sure everything looked nicer than usual). It would only count if you're actually sitting on the assembly line for 16 hours each day or however long they make those people work for the entirety of those 2 weeks.
Also you have to live in the standard factory provided housing with the other workers and not a hotel.
