They are not bound to supply 2 pilots per month, but they do need to supply a few pilots for 2 courses this year.
By phase 2 do you mean the first visit to CTC ( the app being phase 1)? If this is the case I believe it has changed a little recently and there is a coordination exercise involved now. However, they are looking for outgoing personable team playing types. As advised in an earlier post they select an eclectic blend of characters so don't try and be a particular type. If you have the qualities they seek, they will stand out better if you be yourself.
You will be expected to make a short presentation about your background - just sound positive and happy to be there! You will also take part in group discussions. It is not necessarily your opinions that are being assessed but your interpersonal skills. You will have a reasonably straight forward technical paper and a timed arithmetic paper.
Good Luck!
