I am working at the newest hotel right now.It tough to work in a hotel but is challenging.If you really like a service job,this job may be one of your best choices.I have been working in this field for few years.It's not bad.I get goos salary and other things from here.For interviewing here is not too hard for me.I don't know your situation but try the best.The 5 stars hotel in Thailand there are not many,but they are looking for people who have vision and good attitude.When you go for interview,you may approch them by your grooming.You should be clean and waer a little mak up.I wish you get the best luck.
