ATTESTATION
You should begin the "attestation" process ASAP serious about making a move. This  involves your university degree which must be certified at the national level in the country where your degree was awarded, and getting it attested to by the UAE embassy in that same country. If you will be bringing your spouse with you, then your wedding certificate also needs to be attested in the country where you got married. Common-law relationships are not recognized in UAE.

INTERVIEWS
If flown out here for an interview, you may be asked to do a "company" medical including a stress test - this is NOT the "government" medical you will later need to get residency should you get the job: this is simply a quick screen to see if there any major obvious health issues. This is important to employers because of their obligations under UAE law for full medical insurance coverage.

COMPENSATION
Your basic salary may include a set bonus each year - perhaps for tax reasons for US law (other countries do not have dual taxation).

UAE law requires employers to cover basic medical insurance. Your employer may provide  two levels of insurance, depending on your professional level. Since you pay nothing towards it except small deductable for doctor visits, you don't get to choose which package - however there is a wide range of doctors, pharmacies and hospitals to choose from.

The employer also has to provide you with thirty calendar days of annual leave. This typically comes with round-trip economy fare(s) back to the city that you and your spouse were hired from.

If you are subject to U.S. income tax, do NOT stay longer than 30 days, or you lose the ability to deduct the first $93K from your taxable income.
