Dear Asghar u have mentioned, almost, all the areas for the interview to be covered. Here i share some more points.
The first and foremost thing is your confidence. Keep your moral high, no matter, how good or bad your interview goes.
Do memorize the spellings of the typical words i.e cigarette, colonel, committee etc.
Be simple and plain in responding the question asked.
Go through the current national and international issues.
Don't twist your fingers, rub your head or look up and down to recall your memory.

wishing you all the best of LUCK!
