No, wouldn't stand for much. Might make for an interesting but brief topic of conversation at interview.
Interviewers want to see a passion for flying, a spirit of adventure etc. Personally, Id go for the guy who spent 4 years slogging out a meagre living to pay for his flying, gaining a few interesting feathers in his cap along the way.
All this will get you through the interview. Ultimatley it'll come down to a sim test I guess. It'll be the quiality of the flying that gets you though that.
Oh, and to answer your original question.... I think having some A levels is a pretty basic requirement for anything.
