It would be great if some one would provide some guidance on the McKinsey Implementation in MiddleEast?

I am particularly looking to seek answers for the following:
1) How is this practice viewed now, especially in the Middle East? (I saw Q&A from 2020)
2) How different is the salary of an EM (integrative) vs a Solutions Delivery Manager (implementation)?
3) I read/heard that Solutions Delivery Manager is pegged as Sr. Associate internally. Why a step down?
4) Is it possible to switch internally to integrative consulting once inside?
5) How is the career growth within the implementation track? Does it grow into becoming an AP/P as well? Is the pay at the AP/P level still different between integrative and implementation?
6) Are AP/P again split into integrative and implementation, or are they just "Associate Partner" and "Partners"? I ask this because integrative and implementation have different hierarchies at junior levels.

Thank you in advance :)
