While I'm sure there are places where that's the winning move, I think most companies are just fine hiring from the majority of folks who fall somewhere on the spectrum between "agree with everything as hard as possible" and "argue/complain in the interview to the point that it becomes a culture-fit red flag".

If you're looking for technical work and are really getting rejected because of something at the culture-fit level (which is where "agreeableness" falls), I'd say it's less likely that you're insufficiently kiss-ass/agreeable, and more likely that you're being identified as "potential problem teammate" material for other reasons.
