This is not an engineering organization. Deepmind is a research organization led by PhD Hassabis who is the obvious intellectual force behind the organization. All the pioneers of AI from Hinton to Goodfellow have PhDs in AI with a strong publication record. Core AI research is simply not an area where college dropouts like Suleyman can drive research. He is a non technical "manager" riding Hassabis coattails. If Hassabis can get work done without bullying, who is this dude?
