I apply for jobs whenever possible, and usually don't even get a reply of any kind. I worked for one company for 19 years and rose through the ranks from the sales floor to Human Resources at a corporate office. I left on good terms to care for our first baby for about a year. Applied for my old job at that point, was interviewed by the people that I had trained and was turned down. I have applied for multiple jobs at this same company and usually do not even get a call back (despite having worked there for 19 years).
I am not on the record as being unemployed, which I believe is probably more like 20%.
