Cool-gal, are you pretty? lol
Maybe that ah soh not happy to hire a young pretty gal.
sometimes in interview they will do things to "test water", see how
much you can tolerate things.
The boss ask you 8pm go to the office and a second interview, if
you refuse, that means next time something urgent and needs you to
go office to do something, you will not go, even it's urgent. Those
who are willing to meet the boss 8pm means they are willing to help
the company for something urgent in odd hours.
If he make you wait outside the door for half an hour, and when you
come in you look irritated. That means next time if clients make
you wait half an hour, you will show an irritated face to
clients.
