Well, from a candidate's point of view, I think it might be slightly annoying to be told "Hi, we're interested in your CV, but not quite interested enough to actually talk to you. Why don't you take the time to record a video of yourself, and then maybe we'll watch some of it!"

From an employer's point of view, it's hard to see what I'm going to get out of this that I can't get more quickly by picking up the phone and talking to the person for ten minutes.

But maybe I'm looking at this from the wrong perspective. For filling, say, software engineering jobs it may not be all that useful, but for retail jobs in particular it could save a lot of time. Is this person clean and presentable and well-spoken and generally capable of holding a conversation? Well then, this person is 80% of the way to being a good retail employee!

So this is where I'd target it. Besides, if you can land just one medium-sized retail chain you'll already be making a shirtload of money.

Oh, one other thing: I don't like the name. If you were a potential employee and were told to make a video on "replybutton" then the name might confuse you.
