Do you have any tips on how to make this happen? When I graduated I felt like I didn't have much leverage on the job offer, but now that I have a couple years of experience I think I can negotiate a better deal.
And then you're back to how good the candidate's negotiating skills are, rather than that person's skill at whatever occupation you're hiring them into. Companies would rather not think too hard about the moral implications of trying to cheat someone out of what they're worth, though.
If you are a hiring manager, and this is policy, refuse to disrespect the experts you are hoping to entice.
