Very easy interview. I was hired on the spot. They wanted to start training me the same day, but I had to first put in my 2 weeks at my other job. Only high school experience was required for this position; i had my bachelors degree. You will have to take a basic math/reading exam. Brush up on your geometry/fractions/conversions. It didn't matter if i took 3 levels of calculus in college, you will still have to take the exam so they can figure out if you can read and write.
