Has anyone ever worked in Coca-Cola? Do they check diplomas?

Check. Some positions, such as management education certificate, are definitely available and will be searched online. Some job requirements are not so strict, such as security guards and telephone operators, mainly depending on physical age and experience. Ordinary workers in the Coca-Cola factory mainly make coke film packaging. It is purely physical labor to pack the film neatly from the tray to the car or from the car.
