HBS will be notifying all round 3 candidates tomorrow of whether they are being released or if they will receive the golden ticket, also known as an interview invite. I have a few friends who applied in round 3, and I'm so nervous and excited for you all.
Since I technically applied in round 1, but was put on "further consideration" until round 2, I went through the stress of HBS' interview invite day 3 times! Waiting for the clock to strike noon was pretty painful. I must have looked at the clock at least once every 10 minutes starting from 8am. But in the end, it was all worth it, so I really can't complain.
Good luck to you all, and try to get some sleep tonight!
