First off, sorry for posting this without reading that "Where should I post X?" thingy. Was a bit stymied with... you know how it goes, will be more discreet next time :-).
Anyways, being a bit more shameless (deliberately read honest... :-P), I'll throw in my foremost inability.
Well, my GPA is not that good, almost (1.5 .. 2.2)/4, no excuses but just assume that I'm innocent and that I found my stuff more intimidating than classrooms :-).
No, I do not consider myself as some computer genius or something and GPA won't matter to me, but I do consider myself as an above-average systems programmer and I know GPA does matter. But how much does it matter? I mean it would really suck if I step into interview room of a respectable company and three seconds later I come out being rejected because my GPA is not up to the mark.
