I've done a couple of interviews via Codepen where you're watched over video while you come up with a solution, and it's much more difficult than a typical whiteboard interview.
I don't want to invalidate your experience at all, but I find exactly the opposite.
I do a lot of video pair programming, and I feel supremely comfortable screen/video sharing. Getting to work on my own machine with my own IDE and shell set-up, my own hardware in my comfortable home office, 10000% better than awkwardly scratching at a whiteboard speculating about what may or may not work if committed to code.
