I'll say that Jason isn't wrong about telling people "no," but he's wrong about doing it at an interview. They want to see how you act, react, think, etc to get an idea of what kind of person they're interviewing; if the job is very technical, they also probably want to be sure they're getting someone who actually knows their stuff and not just another H1-B nepo-hire. However, the power of "no" is something that should be used, the problem being, it requires a steel will and the knowledge of consequences. I had a HR meeting after butting heads enough with a manager at a previous job and they tried to do the whole "What can we do help you?" I told them, "Let me say no. I know you won't do that, but that's what I need. They keep screwing up and then saying it's my problem, they need to feel the pain of their own mistakes. Let me say no." Had a long discussion about how their tickets are incomplete, so what I setup is incomplete, and they inspect it 10 minutes or less till showtime and always have a problem with me not doing my job and demand I make things right; and gun to the fucking head I have to or I may as well not show up the next day. Let me say "no," nope, can't do that. The one place I did tell someone "no," told them several laws I'd be breaking, they give me the "I don't care," told them I do care, and when you try to get me fired, I'll take you with me. The power of no is good to have, but fucking know when to use it. Someone asks you to show your process and you tell them no, I'm pretty fucking self-destructive in the workplace Jason, but even I'm not that fucking stupid.
Is this just a common type of person?
Phenotypes are real, don't dismiss them as pseudo-science.
There's so many bullshitters because cybersecurity is heavily connected to legal requirements, and government jobs. It's seen as a cost that adds nothing to revenue generation of the company.
Majority of cyber-security specialists in the government are mainly people familiar with security tools and laws/processes/etc. The actual hacker/programmer types who work for the government, are really under Raytheon, GDIT, and others who are contracted to the government. Your day to day guys who man the SOC, let's just say I know two of them who have LTT hoodies. Never had a problem with them and they're personable enough, but they're not turbo-autists, they're a typical nerdy/weirdo/Internet autist computer person; but that's me throwing stones in glass houses.
