Hi... if you have the job you want, it is the main thing isn't it?

If you go strictly by the dictionary, it can mean that you were unusual either in a positive or negative way. However, in practice, when I hear that somebody stood out, I associated with something positive. They were more talented or gave a better impression than those around them. Yes, it can mean something negative, but that is usually explained in the context. If I done hear anything else besides "I stood out at the meeting", I think it is something good.

do you know what exactly stand out means? in my dictionary,it means you are very different,you are not normal,you do something far from the normal rules.so what had you done?

If you stood out in the interview in a positive way, that's great. Congratulations! I assume you mean past tense, here.
