Errr... I don't think this is as nice as advertised. I did a lot of technical interviews (as an interviewer) in a format "show me you project and walk me through it and I'll ask some questions" and for me the most important aspect was that the interviewee used their own computer, their own tools and showed their own project. That made the process as stressless as possible. Here Skype provides a code editor but that can be unfamiliar to the interviewee and may promote questions like "write fizz buzz" instead of deeper conversation about more complex design decisions.
