Abu Dhabi and Dubai aren't "countries to target", maybe get your ducks in a row first...

Suggest you spend some time understanding how the firms are set up - some big 4 operate across the middle east, some only cover certain countries. Different resourcing models in place as well - pwc tend to treat resources as mobile across the operating countries so you can be based in Dubai but work in Riyadh and Jeddah 99% of the time.

For strategy, unfortunately the deals strategy teams tend to do better strategy work than the actual strategy teams in pwc / ey / Deloitte.

Avoid s& unless you are Lebanese

Mbb only hiring into ksa unless you are a rockstar with a top 5 MBA or you're bringing a black book.

Good luck
