I've been applying to jobs non-stop since 2021 and interviewed at many places, and getting no offers. I faced the burnout sometime early last year. I don't have a job, yet the stakes still feel low for me right now. Even for the more "chill" jobs you are expected to pass multiple rounds, and be the best among the candidates.
Just being a finalist isn't good enough to pass, it seems. I would prefer to avoid this criteria of placing first and still find a means of getting hired. For an average developer job, I just want to have an average mindset, not very competitive, where being average among the interview candidates is already considered "good enough".
They want people who can do today's job today, and have potential for more / leadership tomorrow. Even if you just want to coast on by and collect your paycheck... you need to (at least pretend to) be be interested in advancement.
Becoming a freelancer is a booster as it won't suck you into office games.

Perhaps time to take a sabbatical, given financial ability, is travel a possibility?What other types of different work prospects do you have, anything that you find interesting?
You skills; training and/or teaching?
Recharge, refresh and renewal.
If there was a need, even if there were a lot of candidates managers would prefer the first to be enough. But they don't have a need, government policies give them all the time in the world. So for managers it's worse to get the "wrong" candidate than a sufficient one. Managers also prefer multiple rounds, testing, etc, because they can avoid blame by showing they hired someone that passed all the tests. At the same time for managers it's better to get one superstar they can brag about than a person that can do the job, because there is no job subject to profit and loss in the first place.
This is how I explain the current situation, situation I find absurd. I may be wrong, but that's what I think. I don't know if it can help, I think your pain is fully justified and this is my attempt at easing it. It helped me a little, knowing I'm not the problem and nor is the person in front of me (at least not really)
