Whenever I see job postings with salaries this low I always wonder exactly what's going through the minds of the people running the company.

Who in their right mind would want to spend 4+ years working hard on a CS degree only to be offered less than what the average retail manager earns? I barely afford a 1 bed flat share on this salary in my part of the country...

I'm starting to run into more and more job adverts like this. Why are companies working so hard to rip of graduates?
