This is all great advice. I won't pretend that, after a slew of embarrassing incidents early in my career, I've learned to embrace the livecoding interview. No way. I still find the experience stultifying and a bit demeaning. After taking a part-time teaching gig, though, I can confirm that regularly coding in front of a live audience isn't just helpful practice.

This will probably sound hokey or hyperbolic to a fellow anxiety-sufferer, but solving problems in real-time while other people watch kind of... changed me. For the better, I think. In that it fundamentally transformed the way I approach the tech interview. No longer am I the obligate performer of "silly hat dances," but more like... an unflappably cool Jazz saxaphonist at a smokey cabaret, waiting for my drummer to give me a beat. The technical interview doesn't make me anxious anymore because I don't even think of myself as "interviewing" for something — I'm just a musician with an instrument in my hand, trying to figure out if we can make music together, if that makes sense.
