> I think that would be a much more interesting and useful way to spend two hours, rather than implementing cute little algorithms inside an isolated environment like HackerRank. Hiring manager here, one who doesn't use HackerRank either. I'm in agreement with the premise, but I would likely decline an applicant unironically employing the tone of writing emphasized above given the implications against cooperation and teamwork. "cute little" can be replaced with "case-specific" or "niche," maintaining the same general meaning while divorcing it from adversarial connotations.
