At least in Europe, in the industries I worked in, I always had a clause in my contract about releasing company information that was ground for termination without pay and/or damages. Being paid to reveal intel would be ground for termination.
I get it, we all do spill the beans at industry gatherings for instance, even sometimes publicly on hn! I also try and help young graduates get good jobs at great companies but I do it as a former student...or as a side help when I part-time teach classes at universities. (and I pay attention to who I mentor and where I suggest them to apply to)
While I don't agree with this state of mind, I know quite a few companies where a prospective employee is considered a potential asset but still an outside. The interview process is gamed to bring the brightest at the smallest pay possible. Be paid to counter these tactics...not good.
Being paid to essentially deliver intel to an outsider will not go well at some companies.
The interview process is confidential/privileged information. Revealing specifics would/could be in breach of employment contract. Being paid by TheLobby would be actual proof/reasonable doubt that you breach the contract.
(Despite this comment, I like your idea and your personal story and I'm glad someone was there to help you/mentor you when you needed it, I just wanted to expose what was, to me, a potential pitfall )
