In my careless youth during the Jurassic Era, I worked in London, and knew many people who were on the dole ... temporarily that is. In those far-off days, the britgov actually required people to report for interviews at places where there were openings and made sure that (a) the dolee took the job offered ... no matter how lowly, and (b) wanted to know exactly why if that did not happen or a job was not offered.
IIRC, it was a rather effective system in matching people with work. The company I worked for actually hired many people this way.
