Yes. I had one company try to get me to sign a non-compete that would have ensured I couldn't get a job in my field for two years unless I moved across the country. I countered that I would sign that, if and only if (a) I was paid a two-year salary equivalent bonus on hiring, and (b) my offer was tripled since they expected to own everything I created 24/7. They backed down from requiring the noncompete.
