What happens if you answer those sort of questions "yes"?
I like to think you get the job and they watch you closely, assuming you're either a particularly dumb or honest spy.
Oddly, in twenty some years of having security clearance investigators show up to ask about current and former employees, I've only ever had to tell them that I didn't believe someone should have a clearance. That day, my boss (the president of the company) actually refused to meet with the investigator (which should have been telling). I ended up as VP talking to him.
ME: For the first time in years, I'm going to have to tell you that I'd recommend this guy not get a clearance.
GUMSHOE: Why? Do you think he's disloyal to the US?
ME: No, I think he's stupid. He'd give away the secrets to the enemy without knowing he's done it.
I had to explain that not only did this guy give out corporate proprietary information to another entity on a couple of occasions but he also made improper comments about a female employee of one company to an employee of another. He failed to see what was wrong with anything he did. It's one of the reasons we had terminated him.
Alas, it was all for naught, I found out they gave the idiot a clearance anyhow. It's not quite as bad as the guy who quit moments before I went in to fire him and had the audacity to use me as a reference. I get this call:
HR: Mr. Lee put you down as a reference.
ME: He did, did he?
HR: You were unaware of this?
ME: Yes.
HR: Would you like to give him a reference anyway?
ME: It would be better for him if I didn't.
HR: I understand.
