The more popular answers have suggested something along the lines of attempting to recover your losses through legal means. I would suggest that may be a bad idea, as might be something like "naming and shaming". I'll explain at the end.

I've conducted a fair number of interviews over the last 20+ years and the #1 cause of a candidate completely bombing an interview is substantial misstatements of experience, either willfully, or because the position wasn't understood. A good interviewer will try and ease any stress during an interview which might be making things go poorly, but if all of the efforts at putting a candidate at ease fail, resume-padding -- willful or accidental (not understanding the position) -- is usually the most likely cause.

I've had "bombing" candidates go two ways -- they either realize they are a complete mis-match and end the interview (or acknowledge the fact at the end), or they get defensive. In one instance, the candidate apparently told their recruiter we'd accused them of lying (we hadn't -- we discussed it among ourselves afterwards, but no one had implied that during the interview) and the recruiter contacted us. We explained how badly the interview went, and that was that.

I don't know where you are in your career, because you didn't say, but I'm going to share an observation. Quite often early career people assume they can stretch experience because they feel they are ready for an advancement. What they don't understand is how interviewers are often selected. I've been a software engineer for pushing 40 years. I've done a lot of different things, so I've been picked to interview people at 4 of my last 5 gigs. I interview people for competence in their claimed areas of experience. It usually takes me 5 minutes or less to determine if they have the experience they claim. If things are going badly, I have techniques for putting candidates at ease and trying to improve how things are going to determine where their experience lies.

I'm truly sorry you had this experience, because it sounds absolutely miserable. That said, if I had a candidate who completely bombed, word would get back to HR or the hiring manager immediately.

The best reason to chalk this up to a learning experience has to do with the nature of lawsuits. The admitted fact that you bombed the interview will not go well at trial. I'm not a lawyer, but I suspect you'd have to explain how you both bombed the interview and didn't significantly misstate your qualifications. You didn't say they asked you off-topic or irrelevant questions ("I was asked front-end questions, and I'm a back-end developer interviewing for a back-end position", for example). More to the point, if it were determined at trial that you misstated your qualifications, that would manage to follow you around. Attempting to "name and shame" an employer can also go badly. Again, you'd have to explain how you bombed an interview and it's somehow their fault.

My suggestion is to take a long and hard look at the questions you were asked and why you did so poorly.
