It sounds like the recruiter reached out to the team for feedback, and their response was along the lines of: arrogant and unteachable.

Given the choice between a technically superior but difficult candidate and a weaker but collaborative one, most teams will choose the latter or pass on both. In my experience, it's more productive to mentor a coachable candidate than hire someone who dissents at every turn. In a high-performing team, personality fit and other soft skills matter significantly more than many candidates realize.
