I was an SQF Auditor and I did employed work for one company and contract work for several companies and now as a long time SQF Consultant we recommend certain companies and not others as we've been on both sides of the table.
I've sat in on a lot audits as a consultant and have seen the great, good, so-so and downright terrible auditors.
One thing for me that has always been a good "tell" is - does the CB pay the Auditor well or poorly, do they pay on time, do they let them stay in good hotels, eat good food - all in all not treat them badly.
In addition does the CB have a good support staff at the home office and do they have on-going training sessions/calibration sessions with their Auditors.
All of that boils down to either a good or bad Auditor and almost always I've been right on the money (no pun intended) for selecting good CB's.
Currently we suggest our clients use WQS that is based in Charlotte, NC
