Well I popped them an email asking about the project in general (no info other than the general field, which is rather wide and some areas rather dull) and whether I had to apply to all or would I be re-considered for a higher position or a sideways/downward step if deemed necessary at the selection process. Bearing in mind there were actually 6 almost identical descriptions on two different projects, with differing pay scales, they said I had to apply to each individually as they would not be cross-considered. And the email was somewhat "dont bother me with this" despite it saying "for informal enquiries email..." - so I'm not sure I want to apply there now lol.
