면접보러 가서 잘할 것 같아?

Do you think you will be good at interview?

> Do you think you'll do well at your interview?

완전 식은 죽 먹기일 거야.

It will be a piece of cake.

> It'll be like shooting fish in a barrel.

왜 그렇게 자신 있는 거야?

Why do you have such a confidence?

> How come you're so confidence?

내가 그 일자리에 완벽히 어울리는 사람 같아서 그렇지.

I think I'm a perfect man about the job.

> I just think I'm a perfect fit for the job.

그렇다 해도, 너무 건방지거나 거만해 보이면 안돼.

Don't be looked so <cocky> though.

> Still, you don't want to appear too cocky or arrogant.    /왜 이 표현인가?/

안 그럴 거야! 너무 부정적으로 생각하지 마.

I won't! Dont' be so negative.

> I won't! Don't be so negative.

난 그저 현실적으로 생각하라는 것 뿐이야.

I see, Maybe you're right.

> Okay, you're probably right.
