Oh dear, person who thinks it's a breach of human rights to judge people. Guess what? Due to the way humans behave - possibly with the exception of the likes of the US and Australia (i.e. "new" countries) - people have largely developed within their own cultural and language boundaries. It's not racist, it's not bigoted, it's just humans feeling comfortable with what they know. Unless McKinsey can draw graphs showing how the "out of Africa" theory has developed so that male Brits and female Tongans are magnetically attracted and in which case, we could never doubt them as they have a brand, and, like, stuff. So, contrary to what the person above believes, we can actually say with a reasonable degree of certainty that from surnames we know their national heritage in say 8 out of 10 cases and we can tell from their face structure in say 6 out of 10 cases what their genetic background is from experience.As for the "45 nations", in my experience companies that do this rubbish have done so largely counting their admin staff i.e. the Indian secretary, the Filipino cleaner, the Russian masseuse(!). The consultants disappointingly come from a very narrow cultural and social fit profile. Still, it is London, for all its faults, it is one of the most accepting cities in the world. Not having English as a first language is not a problem, people are used to it in the UK and the likes of MacKenzies works around the globe, so posh English school boys only go so far, no matter how loud they speak to the foreigners to make them understand.
