Pros
We got the balance right between being customer (externally) focused and having very high standards of treating our own employees. It's a very demanding environment but you absolutely have opportunities to grow professionally and career wise. Rather ambitious business, and is becoming more edgy which is just great.
Cons
Having worked in multinationals of various origins, I would say that Diageo is very "soft" and no wonder we've been struggling for years with speed of decision making, cut through and real focus. We tend to try and please everyone. Stakeholder management is the skill that would make you successful almost regardless of the "tangible" contribution. This is particularly true within support functions, though I observed it in customer facing, front line departments just as well. Thankfully there currently is a visible shift, and the company is making rather positive changes at the very top, which I hope are going to make a real difference on the culture.
