Have you ever accepted that you were about to have a bad interview?

An hour before my interview. I sit down and realize this is going to be a shitshow.

I had an interview today. I kinda fucked it up. my first big interview in a while but i should've been more prepared

i got 3 hours of sleep and couldn't even get my personality to turn on

chugged a red bull and i still did it cause i'd rather have a bad interview then no interview

still managed to talk about my skills and give my background. however i kept repeating myself. Mumbling words, looked a mess
