Why would they? Do companies have some kind of feel for how many people are long-term unemployed and how many of those apply for jobs with their companies?
Leaving aside data like macroeconomic statistics which do indeed tell companies how many people are long-term unemployed, companies have a pretty good "feel" about people that send them resumes if they read any of them. If three months ago 10% of resumes you were getting indicated long-term unemployment, and next month 2% of received resumes indicate long-term unemployment and 8% list freelancing for the first time in their careers with little details provided and a sample of candidates are unable to provide details in an interview, do you suspect a sudden explosion of entrepreneurial spirit?
