I hired a contractor who thought she had bombed the interview because she didn’t solve the problem I gave her immediately and struggled with it. But when she got stuck it was because she was not seeing that the code she wrote didn’t match the code she described planning to write.

But she didn’t panic, she cracked open the debugger and went section by section through the code until she finally spotted her typo. Which is exactly the sort of person who won’t crumble every time something doesn’t work exactly the way the documentation says it does. We hired six people, and only renewed two, of which she was one. So as far as I’m concerned, I succeeded in my interview.
