I wouldn't read anything into the time being taken for a reply - I think "they" just make it up as they go along.
When I went throught the system in the early 90's it took 4 weeks just to get the results of the aptitude tests due to an "admin error".
Good luck - and remember all the best contollers get in 2nd (or in my case, 3rd) time round. :-)
Let us know how you get on.
