We really are worrying about all the wrong things here. Yes the original email said one thing, then another email something else. After completing the online assessment a message presented saying we would be contacted in the near future with our results. Should we believe that one instead? Who knows.
I'm gonna sit tight for as long as it takes. As mentioned before, they have been known to take several months to call people forward. It's only a small team, and in 2010 had close on 4,000 applications. A safe assumption a similar number again I would think. And for what, 20 positions?
They also have an unfortunate taste for rated peeps. They have to be sifted out of the pile, and probably assessed first. Last time round, the non rated only got a look in much later on.
