Question for the experts, I've been in the quality field for over 7 years. I've done everything from SPC and DOE training to QS-9000 certification and QFD implementation. I recently had an interview with a company looking specifically for a 6 Sigma Black Belt. Not sure if I'll get the position, but if I don't could it be because I am a ASQ CQE without formal Black Belt training? Can someone tell me what's the difference if any?
