Convince the rest of the world to stop applying for senior+ positions and I'll happily stop giving coding exams. Hiring is opening yourself up to complete strangers, literally anyone on the Internet can just submit an application saying whatever they want. Even people with a decade or more of experience end up getting stuck on their specific tech stack and are utterly useless on every other stack. How do you propose filtering through all of that, and why aren't people already doing it?
