I just finished what I think is the best interview I've ever had.
The interviewer was a big fan of the company I previously worked for. I had predicted all of the interview questions perfectly and already had answers planned beforehand.
Whenever I come away from an interview I always think about how I could have answered certain questions differently, or thinking about what experience I should have highlighted more, but this is the first time I've ever gotten out of an interview and thought "yup, that was perfect, no notes."
Now it's going to be extra crushing if I don't get the job, but in the meantime I'm in my happy place mentally.
