Totally agree with you, Sean. It was geared towards candidates who don't even try to find the solution and become content with the brute-force solution. Some candidates don't even try to come out of their comfort zone and that's a red flag.
IMHO both are red flags: candidate who writes only the perfect solution, candidate who writes only the worst solution.
The solution should be a way to discuss (and learn) as many things as you can.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
