If you hold master black belt in six sigma, you might be able to find a job. The key is that you will have to lead at least 10 to 20 projects as your experience from a big company or consulting firms. I am currently working to get my green belt, which is the very first level for this process excellence project. My mentor used to work with GE Consulting. In my eye, he is a smart guy. but he said he did not make big money yet. I guess he is making around $100K a year.
