She basically just throws out bootcamp grads have better soft skills with nothing to back that up.

If that's true, and I've never seen any actual evidence to believe that it is, my guess is that it's because bootcamp grads are older the CS grads in general.

They're usually career switchers and they have experience from that previous career. You really shouldn't be comparing a 35 year old ex-teacher, or a 28 year old law school grad to a 22 year old CS grad on the soft skills front.
