Companies reading my parent comment should take note - abstruse technical questions on a whiteboard are fairly ineffective.

For people looking for alternatives to whiteboarding or phone screens where the candidate writes code in the blind, check out https://coderpad.io

It lets you write and execute code with your interviewee in real-time, and provides a much more native programming experience easily and over the browser. Some rather large companies have started using us exclusively in the in-person technical interview, even buying Chromebooks especially for the application.

Disclaimer: I am the guy who makes CoderPad and am obviously biased.
