However I don't see how they guard against an outdated skillset? My company employees five Infor Sys21 RPG programmers who thought the term "web service" was synonymous with SOAP until I ran a workshop.4 out of 5 worked most of their career for IBM and all have bachelor's or masters in CS, EE, or Math. With a weekend of refreshing they would definitely pass a whiteboard for me (although not necessarily with the most optimized solution). They are all over 50 btw. And work slow and steady (but efficient) with no burnout in site.
I can come up with a "good" solution for nearly every question related to algo on leetcode and have very in demand skills as well as been the top SO poster and core open source developer on a Java platform that is #1 in a Gartner magic quadrant. At 27 and am on the verge of burnout that as happened as a result of getting large Adderall / Vyvanse scripts (legally) and being on the computer for nearly 14 hours every day.
I read this and I wonder if you will understand what I'm saying when I tell you that it is specifically BECAUSE proponents like you fuck themselves up beyond comprehension that I consider whiteboard tests to be a massive red flag when I'm interviewing at a company.
Your career should be a source of service, joy, growth and challenge for your entire life.
Don't destroy it for yourself (and others!) right at the beginning.
So much for the fitness test, maybe we should have one for employers as well.
