interview?

early this year I accepted the offer from *** as a contract officer in this Ministry. I was so happy and grateful for being given this opportunity. And coming this 5/1 I have interview to attend to change my post from contract to permanent. I'm so freaking nervous! I don't know why. Dah lama tak attend interview makes me restless. Nak baca apa ni? What to expect? aaaahhhh. Kalau tak nak pergi camna? hehe ;p takut dan risauuuuuuuuu
