McDonalds is a franchise, so "McDonalds" doesn't hire the workers. Each independent franchise owner does. There are some franchise owners who own numerous locations across an area, so sometimes the same party is to blame for quality and hiring practices. For sure some hire really bottom of the barrel, but I've been to some where the workers were top notch. I remember one lady that was so smart, helpful, and cheerful that I wanted to hire and train her! It all depends on the individual franchise owner's philosophy/approach.
