The place I used to work at hired fresh grads into senior positions exclusively to make the job more attractive. Sr. Engineering (position) had a much wider salary band, so it was apparently easier to hire fresh grads with a Masters degree into those positions, on the lower end of the band, and keep them there for 2-3 years before actually handing out any raises.
We also had very cheap company housing, and a lot of other perks.
