Firstly, just a minor point. Please don't spend 2 whole minutes describing how busy you know he must be and therefore how deeply appreciative you are of his time. A simple, sincere "Thank you for taking time for me. I appreciate it." is enough, followed by some discussion that demonstrates your appreciation. Sorry, rant over!
I believe that a country managing partner sets the direction for the client service and the success of all the offices in that country. So, I would discuss factors that influence his strategy for both of those. Examples:
- The dynamics of the pandemic in that country, how are they impacting his clients and client service. (better, worse, different, no difference). What positive impacts has the pandemic had on his client service? What lessons has he learned? How has it impacted the the employees?
- Social issues in that country: what does he think about the office taking a stand on BLM and how does he make those decisions? How does the office promote women's successes?
Whatever, you choose to discuss, you should be able to demonstrate why these topics are important to you so that you are demonstrating your ability to determine whether the company is a good fit.
Your ability to have relevant, interesting, and purposeful conversation with a senior leader will go a long way to securing the referral you are after!
Hope this helps,
