Dweller, your 2nd paragraph sounds complicated with (personal grade? qu'est-ce que c'est?)

This is what well informed sources tell me:
1. CEO: JG23
2. Senior Management: JG20 to 23, for Qatari nationals only.
3. Senior Staff, Expats: JG14 to 19max!
4. Other staff: lower JGs.
Quality of life Re allowances: proportional to JG.
