Another thing I say is that everyone should try to help one colleague in a way that helps them achieve a little bit more. It need not be work. It can be in any aspect of life. And part of it is that you have to be open to it. If somebody says, “Hey, I see you’re doing that, and I can give you a tip,” the person has to be open to hearing it and to want to hear it.

I’ve been pushing that message for five years, every day. Everybody has to take some accountability for other people, and look for ways to make small contributions to help others. Looking after people has to become everybody’s responsibility. Innovation and caring for people are cultures; they are not departments. It takes time to build that culture.

With such a large company, it can be easy for silo thinking to creep in. How else do you guard against that?

When I took over as C.E.O., we split the company into 23 units, because I wanted to create a very flat but empowered structure. But we also made it clear to the leaders of those units that we expected them to work together. We said the power of our company will be driven by how well they work together. In some of our bigger monthly meetings, we will start with people presenting examples of their collaborations.

How do you hire?

I want to know how the person articulates their strengths, weaknesses and what they’re looking for. The whole idea is to see if there’s a fit. To me, the fit will require the person to have passion first. Then I want to see if they’re a team player.

What is your best interview question?

What do you want? If you were to spend the next 10 years working here, what do you want? I’m looking for clarity in their answer, in one or two sentences.

What career and life advice do you give to graduating college students?

The first thing I tell them is that when they are in college, they often look for the best-paying job. There’s nothing wrong with that. But in the first few years, you very quickly need to know what you want to achieve in your career, directionally. Otherwise, you can end up hopping around and making some money, but after that you’ll feel dissatisfied.
