Two things...
One, that's what youngsters do. So unless you're in your late 20s/early 30s, that bullshirt. It's a real issue, but it's also a generational one.
Two, if an employer is openly telling you that, trust me when I say you didn't want to work for them. I would never say that to any candidate and would rip a hiring manager a new one if I found out they said it.
