I had a company (perm position, not consulting) that got all laywer happy. Over the two years I worked there I think there were 4 or 5 rounds of NDAs, each which superceeded the last. The NDAs had a lifespan of X years after leaving the company.

There was also a professional conduct document, which included a "non-competing clause", that you couldn't do the same thing outside the company that the company did while you worked there.

Then they combined them into one document. Which if you looked at it with a critical eye you agreed not to compete for the life of the document, which lasted for X years after you left the company.

I (and several others) told them straight in the eye we weren't signing it. They told us that our continued employ at the company hinged on the documents being signed. I got out of there fast.

Details may be hazy, it was a while ago, but it was just an ugly situation. Even if unenforcable, it was still something I wasn't willing to sign away.
