Can't wait to bomb this interview tomorrow morning

I have a 45 minute technical interview with no other details provided. I have no idea if it's a "soft" technical interview where they just kinda ask me the usual questions like "what would you do in this scenario" or "tell me about a time this happened" or a "hard" technical interview where the questions are more like "implement a red-black tree with unit tests and documentation." I'm mildly prepared for either but either way I'll be at least partially winging it.

Interviewing isn't as bad when I already have a job and there isn't as much pressure but man it still fricking sucks so much.
