I've moved your post to the Dubai forum now but you originally posted in the Abu Dhabi forum asking about Dubai, so I'm not sure of the exact information you're after. So I'd advise you to have a look at the Expat Arrivals page for Working in Abu Dhabi and/or the one for Working in Dubai. These pages have some information which will help you get started.
I can't say at all whether your job offer is legitimate or not, but from from just a quick Google search it does seem Chida International Hotel in Dubai is an actual hotel. I would try to get in touch with them directly using contact details on their website to verify the offer.
Otherwise, the best ways to find a job in Dubai are using internet job portals or looking at opportunities for an intercompany transfer from your home country to the UAE.
Read up about the economy in Dubai on the Working in Dubai page.
