I am too poor to open a development company. But, if I ever did, I would want it to be employee owned, with employees having power to oust the entire executive team. Clients who don’t wanna pay are too fucking common.

I have never got a job that required a live coding challenge, yet I've worked for major Fortune 500 tech companies, and have advanced my career about as far as one can go. Thankfully there are plenty of jobs that evaluate your merit based on what you've done in the past, and what you know, instead of whether you magically know if they want recursion or not for a deep loop in some obscure coding challenge that has little in common with real world problem solving.
