Imposing that on companies by whatever means(legal, social) will lead to less hiring overall to make it low risk. As much as it sucks to get laid off, I am sure a lot of laid off folks who were hired in the last 2 years would be glad that they have Google on their resume. That will set them up for a good career, since Google is known for a rigorous interview process.
So, going through a rigorous interview process is indicative of expected performance on the job? Shouldn’t the work they did for two years matter more than the few hours of interviewing and solving puzzles?
