In reply to Jackob:
Abu Dhabi is a pretty expensive place to live - it's at least a tenner for a pint in most hotel bars so don't expect to save very much. On the plus side, cars are cheap, and so is fuel and there's no income tax currently.
Work-wise - check the T+Cs about the role, working hours/days, accommodation allowance, travel allowance, flight allowance and holiday allowance. These need to be listed clearly in your contract. Your prospective employer may say not to worry about such things, but make sure it's all written down. For example, the accommodation allowance might not be enough to rent somewhere acceptable, so do your homework. Ask for as much salary as you dare - if your experience in the role is significant, highlight that as much as possible.
It gets stupidly hot/humid in the summer. You adapt over a couple of years, but your first summer may feel unbearable. 50 degrees is normal, with no chance of outdoor climbing from May to September, except for the couple of hours, in the shade, immediately after dawn.
However, I reckon it's the most pleasant of the emirates - much less built up than Dubai. My trips there have all been for golf, flying in from Saudi for long weekends, so I can't comment on the climbing locally. As others have said, Oman is very, very good for climbing and a generally nice place.
Note the current covid situation. Flying out of the Middle East was very restricted for most of last year so there's a risk of getting stranded. I couldn't leave Saudi for 7 months.
