As a hiring manager I think it would be valuable to see a Video Job Interview of my candidate, prior to the actual interview. Reviewing resumes and phone interviews are part of the interview process, but actually seeing the candidate being interviewed on video and responding to questions would add a valuable element not previously available.

Some advantages of viewing a Video Job Interview for a hiring manager are:

More valuable information with minimal time requirements.
A test of the candidate's ingenuity and ability to use current technology.
The advantage of viewing the candidate answering questions in a somewhat stressful situation.
The ability to see what a candidate deems important and an idea of what type of end result (The Video) the candidate believes is a job well done.
