Andrew Gould, CEO of oil-field services giant Schlumberger, presides over 80 offices worldwide and a company that, as he describes it, has no national identity. In this video, the latest in our interview series McKinsey conversations with global leaders, Gould shares his views on why leading such a global company successfully requires a belief in meritocracy and equal opportunity across geographies, why oil production will remain strong despite the rise of alternative energies, and why science and innovation form the bedrock of Schlumberger. Ivo Bozon, a director in McKinsey’s Amsterdam office, conducted the interview.
