Agreed! My thought is that if the interviews/visiting day have passed, which means they already have a shortlist in hand, then there's not much you can change. If you got interviewed you'll be fine, just give them some time (though I don't know what's taking them so long this year!!)
BUT, if you're not contacted and you know for sure that they are still SENDING OUT interview emails or still DOING interviews , you may give it a try!
