You read that right. Many ovens, new or old, have hot spots which makes for uneven cooking.
If you constantly have issues when baking, things are uneven and have brown spots on them, hot spots could most definitely be the problem. SaBrina Bone, who tests in the Cooking Light kitchen, advises the “bread test:” Arrange bread slices to cover the middle oven rack. Bake at 350° for a few minutes, and see which slices get singed―their location marks your oven’s hot spot(s). If you know you have a hot spot in, say, the back left corner, avoid putting pans in that location, or rotate accordingly.

Smart. I would have never thought of that. Good luck testing those hot spots! Let’s hope for minimal to none.
