For those interviewers and candidates looking for a better solution than the "google doc shared whiteboard" - I suggest checking out a product I make: https://coderpad.io/
You can think of it as a much higher fidelity Stypi, Etherpad, Collabedit, etc, except that you can run the code in the browser as you write it. It really helps alleviate the choking sensation of being asked to write out an entire problem on a whiteboard without any of the modern affordances we've come to know and love.
Yeah, this actually did seem to lead to some confusion, which was the first bad sign. Google Docs obviously doesn't know how to format code, and the indentation was getting messy during the typing process leading me to have to break, think, fix indentation, resume thought, then answer to the questioner about my "preference for three spaces or two"... ? It was an obscene process that could have definitely been refined by your app and possibly led to a better outcome.
You wrote that? I love that site! I actually saw it for the first time last week when a company I was interviewing with used it as part of the interview process.
I loved how smooth and fluid it made the whole process, that they could switch between languages during the interview and the rewind functionality.
