My best interviews were the two where I was calm, relaxed, and myself. And I was offered the job each time.
Granted these interviews were for a better job than the one I had, but, at the time, I had a pretty good job and didn’t technically need the one I was interviewing for. That allowed me to be more relaxed, I made a few well-placed jokes, and was just myself, which is ultimately who you want them to hire anyway - the person you really are, not some stuffed shirt, stiff version of you.
