There are certification companies that take people in and train them. It's not very common these days because there are so many "auditors" out there, but it's not unheard of.
I'm not sure what you mean by "zero experience", but people have to start somewhere. I am a biologist by education. Many years ago I got into the business world by applying to a company looking for someone with experience with a specific Mil-Standard. I had none, but I got a copy of the standard and called the company. I got an interview and was hired on the spot over some people who had experience with the standard. In talking to my boss later on he said he hired me because of my initiative of getting a copy of the standard and by the time of the interview I could tell him everything about it, it's requirements and how to carry them out. I had also researched their product line and could discuss how the standard applied to their products, required testing and related information.
Each person is different. I stand as a person who got a job with no experience in the field who got that job over people who had experience.
Tracey's son is another example. He got his masters in math and statistics. He had no biological, much less medical, background. His first job out of grad school was in medical research at a salary of over US$70K. He had a lot of job offers (Wright-Patterson in Dayton, Ohio was one off the big bidders if I remember correctly). None of them cared if he knew squat about their industry. They wanted his ability to work with numbers. He chose the medical research job (out of quite a few offers) because he wanted to work in a clean, quiet place.
Experience is only part of the equation, and many times it isn't the deciding factor.
That said, some of this thread is about consulting. In consulting it is different in that *most* consulting does require experience in the field. But again, it depends upon the type of consulting. I have done a lot of consulting in business standards and business systems - Everything from call centers to general manufacturing to high reliability aerospace device companies.
One the things I loved about my career is I went into so many different industries and saw (and learned) how they were run, including many, many different types of processes. With each new experience I built upon my areas of expertise.
As a last thought, I have a friend who got a job with P&G right out of college. I forget what he started as, but it was a rather low level managerial job. Over the years they moved him to many different facilities around the world where he learned how they did business at different facilities, including different products and different processes. He retired as a high level executive a few years back.
