keep going for a while bah.

maybe the interview skill,
do you know why you fail?

currently there are still pretty people with experience on the job market bah.
so if you want to compete with them, try to make yourself impressive.

certificate may help you too.
Actually i think if you got chance of interview,that's already pretty good.
Is that ur spoken english problem?or technique question?or interview skill?

you don't need to be smart, just need to show you are perfect for the job,:)
