I turned down a job offer because it was about 10% below what I wanted. Four months later I saw the company complaining that they still hadn't filled the spot - I wonder if they think they made the right choice in refusing to negotite. (Probably they do, and they continued to do so with other candidates).
I keep seeing the same ad for a job that I was contacted about a few months back. I refused to do their hour and a half hacker rank challenge on the basis that is nothing like how I work on a day to day basis, and I have examples of real work online if they need to see that I can code.
