> I mean - there’s an industry around how to do well in programming interviews

A ex-Facebook employee who's an acquaintance runs a highly successful business that employs 250+ people, bootstrapped up until recently when they took in $1.5M in angel funding at $20M val. They aren't that big as there are even bigger players in the market. I'm not sure if existence of such shops is a good indicator of the state of hiring in tech. Also, such business seem to be optimising for a very narrow goal unlike https://podia.com which is a wonderful platform for creators / tutors to monetize their content.

Despite the existence of books, websites, and MOOCs with arguably better content and community which are cheaper or even free, I've seen many instead opt to pay companies that help tame tech interviews. I guess, people only value what they have to pay for.
