At this point, there is a whole industry (I don't know how much it is worth but I assume in the order of billions) that sells you courses, books, articles, bootcamps and so forth with the sole purpose of preparing you for tech interviews. SDEs themselves are quitting jobs to sell you their courses. The surprising thing is that, as a self-fulfilling promise, these leetcode questions + system design questions have become the standard for most jobs. I said "surprising" because even after a CS degree and over 5YOE, and plenty of projects/achievements to talk about, the algo questions are still as important as in your very first job interview. Sure, expectations are higher in other areas, but the bar for leetcode questions is still there and it's a pass or fail. Obviously, no one working on actual SWE projects has to use the same type of skillset required for leetcode, which ultimately gets rusty and each time you change jobs you have to waste a massive amount of time doing it all over again. Hasn't this gone too far? Isn't it a bit excessive to test senior candidates on undergrad algo brainteasers questions? It seems to me that it's a cycle; in order to change the job you grind leetcode for months and then when you interview candidates it is automatically the thing you expect. What do you think?
