First off, make sure Skype works on whatever computer you plan to be in front of during the interview. I know this seems obvious, but trust me on this one: check and double check so there won't be any unforeseen technical difficulties. You know what they say about people who assume.
Before I get started, I want to make it clear that I'm not just going to tell you exactly what happened in my interview, because that doesn't seem fair. What I can do is tell you all the dumb things I wish I hadn't done and the useful things I wish I had done, in hopes that you will have a better time of it than I did.
Honestly, you probably don't need any help with the application itself. It's pretty straightforward, if horrifyingly long and annoying to fill out. They've changed the format a bit since I applied, but the basics are the same, so I'll go through the whole thing and point out whatever seems important or confusing.
The snow is melting, yellow dust has begun to float in from China, students are shedding their winter padding coats, and you know what that means...EPIK application time! Or, you know, spring. Whatever you're into, really. Dumb jokes aside, I've been meaning to do a series of posts with advice for aspiring EPIKers for a while, and like they say, there's no time like the present.
