> Basically for some random reason, the thought pops into your head just how disastrous it would be if you failed at this thing you're being asked to do. Then your consciousness inevitably becomes obsessed with this thought and it's all you can think about. You start panicking

This happens to me all the time! You’ve described it so succinctly. How do you cope?

Some perspective from the interviewer side: just tell us straight up that you're panicking. While I can't guarantee that an elitist smug interviewer is going to always respond appropriately, I at least would make an effort to try to help you calm down, be it by removing trivial blockers (e.g. fixing some syntax blooper for you) or trying to paraphrase whatever you're trying to say but not finding the words for, or asking leading questions in the hope of bringing you back on track. A little dirty secret among interviewers is that we're supposed to be accountable for managing the direction and quality of the interview (i.e. one that devolves into a awkward staring contest is a failure on the interviewer's part for not interjecting appropriately)

Ultimately, it is in the company's best interest for an interviewer to look past things like nervousness-induced panic attacks, and I've heard on numerous occasions that good interview sessions involve the interviewer and candidate working together rather than adversarially.

Slow breathing exercises and grounding (e.g., look at the things around you and name what they are) work well for me.

Once it gets past a certain threshold it gets harder, so being mindful that one is coming on and routing it before it gets into a positive feedback loop is very important. Leave the situation you're in, e.g. tell others that something has come up and you have to go.
