Hi unprettyangel,
Dont get nervous. Once you get in there things will seem to be much more simpler. You jus hav to submit ur cv, along with your recent passport and full size photograph(avoid white background) your latest updated resume and an id copy/passport copy.they will ask you
how your doing ?
How to address you?
Your currently working or not ?
How old are you ?
Which phone number you would prefer getting a call ?
So you dont have to wait there once your done. You can go home, relax and keep your fingers crossed to get your invitation call.
All the best for your interview :-)
