I don't think that's true in the sciences. From what I've read on this website, you have an impressive resume as a scientist (although I'm not sure in what discipline -the biomedical sciences?) so I'm surprised by your take on this. I have some experience in that field, as an undergraduate major and in working for a pharmaceutical company, and it seemed pretty clear to me that there was no real advantage in a gimmicky undergraduate major like "neuroscience" or "genetic engineering".
Our experiences -- and companies -- may differ. And much of my corporate
experience was quite a spell ago, and the culture may have changed
(although my understanding is that it has changed for the worse -- making my observations more true rather than less).
One key inter-company difference that might explain it is the amount of autonomy given to the HR departments for pre-screening. I'm not going to name specific companies here, but I will point out that the first company I worked for post-baccalaureate kept HR on an extremely tight leash, even for lab tech/BS positions, and most of the recruitment was done through personal contact with individual colleges. HR was basically reduced to a record-keeping organization, and wasn't permitted much flexibility even there. Probably not by coincidence, it was also one of the least business-oriented and most science/tech-oriented places I've ever worked for. They tended to hire for the long term and didn't mind hiring "outside the box." But that attitude is (in my experience) most notable for its rarity.
Almost everywhere else I've worked -- or attempted to place students -- HR got in the loop too early and started whinging about lack of specialist credentials (as though a post-bac intern can get "specialist credentials" in coffee serving?)
It may also reflect the relative quality of our students and/or schools. Neither MIT nor Oxbridge needs gimmicky disciplines to place their students because the name itself has street cred. Things are a little different further down the food chain, where it can be hard to distinguish South Hudson Institute of Technology from Sam Houston Institute of Technology.... But a degree in left-handed genetic engineering might help....
