@dreamlinerguy:
Having a deadline on an aptitude test is no different than having a deadline on an application, or an exam or anything else for that matter. I'm sure the recruiters in Jet2 didn't sit around the table and wonder how they could cause the most inconvenience to you.
Presumably as you are posting in this topic, you are interested in the scheme - however the attitude you display in that post speaks volumes. The world (and Jet2's recruitment) doesn't revolve around you. There will doubtlessly be hundreds of applications for very few positions, therefore it would probably be in your interest to make time to do the aptitude tests, and do them well, not just "get around to it".
Aptitude tests do have their uses, if only to weed out those who can't be bothered to jump through hoops. You'll have to jump through hoops your whole career in this industry, and virtually every flying job you apply for - in the airline world (which you presumably aspire to looking at your username) will have aptitude testing of some description as part of the selection process.
As a final note, you are presumably still quite young, and looking to get into this industry, I wish you the best of luck but the attitude you displayed in that post won't get you anywhere, and recruiters have been know to frequent these forums in the past.
