Its nothing..congrats you've been hired.Just chit chat nicely with the director.. All the best!

Hardship allowance is counted daily - amount of days that you're participating on-site ( out of Malaysia) for that project.
Whether or not you travel depends on your ability to independently handle projects. Your project requires heavy travelling, so you should be flying in no time if you learn quick. Global means global, pretty much speaks for itself, SP means countries in SP region.
You don't have to OT until the wee hours IN the office per se, you can bring it home and do.
Make a good impression and you'll most probably get the job. But it really depends on the director. This is general advice, Don't stress it out, if the director doesn't like you and you don't really like him either, chances are you'd end up hating working for him anyway.
I've personally known at least 5 candidates that passed the technical and HR but failed the director's interview. Don't count your chickens before they hatch

the interviewer not so good english speaker

its a 13 month salary but the my expected salary was not accepted.

so i dump it
