Can a person really know ALL this?

I'd just mention, it's the sort of thing that puts interviewers off - when people lie. We suspect you aren't telling us the truth about other aspects, when you fail to answer basic questions about the tech that you supposedly are knowledgable in. They often have someone like me in the interview, someone technical. We poke and prod to see what you know, and if you don't know something and own up to it - that's totally cool, we get that. But we do read your CV, and if you claim to know something and can't answer a basic question - we feed this back to the hiring managers be it through subtle signals, or in a quick chat whilst you're doing some form of test.

It's not worth taking the risk of someone who has been duplicitous. Fine you say you can google it, but the reality of hiring people like that (in my experience) is that they fold real quick, or bother other people in the team with basic questions. We didn't hire you as a junior or an intern, you're a dev/qa/software engineer.

We're far nicer to juniors, but someone who sells themselves as a senior or mid-tier needs to back up their claims. I like to put those claims to test in interview.
