I remember how stressful this period felt last year, constantly checking student room and my email. So in case anyone is in that state now, some FYIs
I got my interview invite on the 30th November. They dished out the invites very slowly. They also stopped sending invites out over the weekend and resumed the following Monday. I remember the agonising wait over the weekend.
So try not to stress, it could be a while yet before you hear, definitely don't panic when you start seeing people get invites if you haven't had yours. It really takes a while for everyone to get their invite.
Best of luck everyone, I know this time is really stressful. Try to relax and have as much fun as you can while you can in case you are successful!
