Yes, they were advertising the posts in the 1960s. I was tempted but not keen on the 2 year contract, and I knew b*gger all about general handyman work including maintaining 2 stroke engines, a pre-requisite, so my career took a different course.
I have always regretted not applying for it when I was a young man.
