Long time lurker but I decided to post on this since I can offer a decent perspective and do have rather strong opinions about Dubai. I'm 24 and currently working in Dubai. I've lived here for a year now, and previously worked for the same company back in the states for a year before moving to Dubai. I was born and raised in the US, and am Chinese. (though unfortunately come across as Filipino all the time over here)
I can agree with the majority of what jai3368 said. Do not intern in Dubai, it's pointless and yeah, you'll be paid virtually nothing. If you want to work here, have an actual job. You would not be able to survive here on an intern's pay here. Rent alone can be about $2,000 - $3,000 a month for a decent one bedroom apartment, with rent costs increasing something like 15% a year, which was true in my case when I re-signed.
In regards to engineering opportunities, they are there, there are plenty of job opportunities available I suppose, though I know in the finance side there are a ton more.
Dubai has its highs and lows. Sometimes you think the place is absolutely amazing with the stuff you can do here, but at other times it's a damn depressing place. I would be considered a rather senior person in Dubai having lived here a year. It is an extremely transitory place with most people not staying more than 2 years, though there are some people that get completely caught up in the Dubai lifestyle. In general I would say it's extremely superficial, which I suppose is obvious to any outsider.
Unfortunately many of the posters above are wrong about their assumptions about Dubai. Dubai is definitely one of the most progressive areas if not the most in the entire Middle East, and is extremely Westerner friendly. That aside, the class disparities and some customs will absolutely disgust you too. There is a fair amount of media censorship and control, but it's something you just have to get used to if you're going to live here.
This place has definitely been an amazing experience for me though, I've grown a lot the past year, and plus it's going to look great on the resume. Dubai can be a great place for certain people, but others will absolutely hate it. Also, the adverts and everything you see about Dubai is just one narrow aspect of the real Dubai.
I've been here for 1 year, and I think after another year it'll be enough for me.
