Hello,
Congratulations on receiving the two offers!
It depends on how you value the following elements:
1) Short-term vs Long-term: Are you in consulting for long game or just want to spend 2-3 years and leave? If you are in it for the long, you should not be tempted by a higher position being offered now as eventually you will make up for it in the long run. You should ask yourself - do I see myself as a Kearney partner or an ADL partner 10 years from now
2) Prestige: I think from this point, you have clearly identified Kearney as a winner
3) Geography: Although ADL has its legacy, Kearney is more popular worldwide. If you ever want geographical mobility out of the middle east, Kearney's brand will help you more
4) Exit opportunities: Linking back to point 2. Kearney commands a higher respect in the market
5) Culture: This is something that you need to assess carefully. Do you think you will be happy in a mid-sized firm where everyone knows you personally? Or would you rather be in a bigger corporation where you have more training opportunities, larger projects, but are a smaller part of the firm.
6) Clients: Just strictly from a middle east perspective, Kearney has a much higher market share than ADL.
All the best!
