I have no idea what truly happened but it seems:

    1. younger person finds *rock star* older person
    2. older person says yes, then says no, and says 
       well I am not impressed enough with you
    3. company says report to a higher up, and we will 
       vp'gold you
    4. younger person says sexism!

It's an interesting claim but Occam also suggests it could be ageism + way better offer. Do we really know this older person would have accepted the same offer from the equivalent male younger person?

I think it's great she has a coach, honestly, I am not sure that's a privilege many of us have.

I don't know who this rock star was or where they ended up, but meebo, didn't that finish as an acqui-hire?
