INTERVIEW

When for my first interview. Well, the interview did goes pretty well... except when I thought its ending.... I was told to attempt a short test... right..

and basically i failed the test.... I wasnt prepared for it! zzzZ
all the programming, pointers, OS stuffs....

Its a good experience still... but netherless felt abit lost....
I wonder if software engineering is for me =/

which direction should i head for now?
