They invited you to an Open Day. You attended the recruitment event, you cleared the First Group Activity, you did the Second Group Discussion. Then, after the break, they tape a sheet of numbers to the wall outside the meeting room — and your number is not on it. Your day is over, and nobody explains why. Or the invitation never arrives at all. Either way you wait six months and try again, without ever knowing what went wrong. I sat on the other side of that table. I will tell you exactly what we were looking for.
