Trending @Accenture; How many years does it take to move from senior analyst to specialist level i.e., 10 to 9

What is the criteria, any idea how they consider in general

Overall impact in project and value creation, also good people skills play a crucial role. It also depends on the primary skill, some skills are more sought after and therefore demand a higher premium.

I joined as level 10 with 7 years of experience 🥲

If for TL is 6yrs of experience then what for level 10? How much year of experience needed from level 11 to 10??
