Cons
Very little impact of the organization, too much arrogance. This entity organizes VIP events, nothing else. Absolutely no consideration nor reward for junior and mid-level staff. You're just the next one in line. Don't plan a career there, it's not the point. Try to find your niche within the organization linked to your passion or expertise, and give yourself a few years. Then go. Run away from projects branded as the next big thing by the Chairman, they're too unsustainable, badly managed, and subject to constant change, when they're not purely and simply cancelled over time. This organization suffers from an over-concentration of decision-making power in the hands of its founder and current Chairman (for more than 40 years). It prevents it from reforming and modernizing itself. It's one of its biggest long-term risk.
