Pros

- amazing people - learn a lot about how fortune 50 companies operate - fast paced, never a dull moment - best practices, conferences and retrospectives continuously being improved upon - nice offices and benefits

Cons

- solutions barely go beyond random forest, and are simply ‘transactional’ i.e building models is all Partners care about, not integration. - becoming McKinsey & Co way of working more and more every day i.e ‘up’ or ‘out’ promotion mentality - you are punished for not thinking pyramid principle. - the company is treated like a ‘functional department of McKinsey & Co’ now, where people move on from project wins but interrogate failure. - expect late hours and weekend working where you are questioned for not giving more than asked for. - executive committee hardly visible to the people who hold the company together.
