The worst interview of my life was at Meta, and it was bad enough that I have permanently blacklisted them as a place I will /never/ work. I get contacted by Meta recruiters relatively often despite the fact I let them know after the fact that they were horribly unprofessional and I would never work with them after that experience (setting aside any ethical concerns, which I also have).
I've had several other bad interviews in my career though, and almost all of them were small companies / startups. It was also obvious, sometimes in the moment, that it was bad because the person interviewing me lacked the maturity, experience, or professionalism to be conducting interviews of anyone. Many times that person was the founder. I consider those all dodged bullets.
It's always important to remember that interviews are a two-way street, and the way someone conducts an interview can tell you a lot about them and about the organizational context they operate in. Do you want to work there?
