Pros
Nothing you couldnt get elsewhere.
Cons
Relevant to the 3% in the UK.(12% in US) Top four levels of engineering are near 100% W-SEA-SA. Check FON. Reflects decades of racist hiring and promotion practices. Preference in hiring African graduates to boost race ratios. For two reasons. No one on a visa is going to speak up about racism. The opposite. They will support the racist work culture. And two, they can pay them less than a visa candidate from SEA/SA. Hostile work culture. Racial codes and signalling. Pocket tapping, bag clutching, ignoring you in meetings, harassment from security, false accusations of theft, racist language, segregating into race dominate teams. All SEA/SA teams but never all AA/AD. Walking through the London office is like walking through a neighbourhood you don't belong in. I suspect if desks could have hazard lights and alarms, they would be flashing/going off as you pass by. Don't trust HR or any Diversity Advocate / outside agencies / charities. Especially if they say its anonymous. They are all there to protect the company in case of litigation / media attention. Get a lawyer/solicitor instead. All comes from the founder, Micheal Bloomberg. No surprise he came up with stop-and-frisk, which was then copied by the UK with stop-and-search.
