Looks like you have another interview somewhere else though, right? So, if you haven't done that one yet, maybe you can take what you learned into the next one?
Anyway, I'm sure you did great. Everyone there, at least that I met, seemed really terrific. I don't know how they'll make those choices! I know that the people who are accepted should know soon (maybe by Monday....?), but I wonder how long it will take for everyone else.
Remember that quote from Shawshank Redemption about time drawing out like a blade?
