I havent experienced all of Dubai nor do I live there, but I have been going there on a fairly regualar basis lately, mainly just passing through, spending a night here and there.
 
The last time I was in the cab, I asked the driver about crime in Dubai.  He told me it was next to nothing, says it is very safe.
 
The few times I have been out driving, I found the traffic to be a complete nightmare. When you get there, youll get the feeling that a lot of money is there. The whole place seems like one big construction sight, with high rise condos and office buildings dotting the horizon, under construction.
 
They have a few large, ok, enormous shopping malls.  Ive been to the Mall of the Emirates a few times, its bigger than anything ive seen, even has an indoor ski slope in it.  Lots of shops, youll find anything you want there, for what I thought were reasonable prices.  
 
The airport is nice, at least terminal 1 is.  Terminal 2 isnt as glamourous, usually caters to the flights headed out to some non-desirable locations.
Terminal 1 has a lot of duty free shopping in it, nice place.  
 
And its warm there now, not as hot as it was a few months ago, the humidity made me stop in my tracks when I hit curbside.  
 
I dont know if you already have a hotel, but Ive stayed in a place called the Traders.  Nice place, reasonabley priced.  
 
And the best part of the whole place, is that in the cabs, when it stops at a stop light or in traffic, the meter stops running, so it isnt terribly pricey to get around town.
 
Seems to be a fair number of expats there living, some ive talked to enjoy it a lot.  
 
Ill be going there tomoroww again, no hotel, have to sit from evening'ish until 4am to catch the next flight.  I think theres a place to get a shower for 10 bucks in the airport. We'll see. Good luck on your interview.
