Interviews, and in fact, most first meetings between people, are often shibboleths: a perfunctory test of similitude to prevent outsiders from getting in and causing unnecessary angst by thinking differently. (In Biblical times, apparently, the word "shibboleth" could not be pronounced by The Other Tribe, who pronounced it "sibboleth", and were denied entry or worse, killed by the guards).

If you're OK with this, then interviews can be an enjoyable game with rather predictable behaviours (and even predictable questions, probably taken from "Cracking the Coding Interview" or equivalent online course). You just have to learn to jump through the hoops. Just look at leetcode or google, "how to pass tech interviews" and pay up for a course on it. Just remember to not roll your eyes during the interview. (The real issue arises if you start hating this process or the thinking behind this in the industry).

You could get lucky and find employers / interviewers who assess general intelligence, or better, find employment through your network of friends, ex-colleagues, and mentors, which would bypass this process.

All the best!
