I mean yeah, you should lie in interviews. Mind you I don't mean make up ridiculous fabrications like "I single-handedly saved the entire company from bankruptcy", more like little white lies and twisting of real truth to make for a better story. It's unfortunate that that's how it has to be done, but it's an adversarial circumstance to begin with, so I understand why people do it even if I'd prefer to not have to.

Companies absolutely will lie and cheat if they can get away with it, for example by saying their hiring budget is only X amount for the role when the recruiter knows full well the real budget is X + 20,000. They will absolutely lie about things like PTO and flexibility. So there's no reason for you not to also engage in it, because you're really only screwing yourself over if you don't. It's unfortunate, but that's the system we've built.
