I have a sneaking suspicion that this is not the case. Companies that want top talent and are willing to pay for it are not shy about that fact. Seeing a legit job posting for a position that pays double your current salary is a solid incentive to apply.
I'm guessing that the subject of this interview probably makes a less-than-competitive salary. Programmer pay has handily out-paced inflation for decades now. She probably started at around $30,000/yr in 1991, if she managed to get a 3% raise every year, that would only bring her to like $63,000/yr.
Naturally, I'd love to be wrong about this. This woman has a demanding and important job and deserves a generous salary for it.
