It was a remarkable place to work. "Bill and Dave" were household names: I was really struck by how much of their vision and values had been embedded in the firm's DNA. Quite amazing for a multi-national.
I remember the UK general manager coming to visit our site. He wasn't immune to the usual entourage of hangers-on, but always insisted on going walkabout on his own for an hour or so. Precisely so he knew what was actually happening at the coal face, not the filtered and abstracted artefacts of managerial reports. He stopped to speak to one of my colleagues - a recent graduate. The grad had no idea who the manager was, and asked him politely to give him 10 minutes as he was waiting for a build to finish (1990s remember). Those of us who knew the manager were aghast and assumed the grad would be in for a bit of a tough time. But the GM just smiled and said "of course, hope it compiles OK", went away, and came back later.
That moment has stuck with me throughout my career. I've sought to emulate that level of humility and respect. Can't say I've always been successful, but it remains inspirational.
