Pros
BCG promises to invest in their employee's growth & professional development and they 100% make good on that promise. I get tons of feedback, regular reviews, and training at key points within my career trajectory. Everyone who I have worked with cares that I am developing and building my skill set on a case. Working at BCG is a great way to get exposure to a lot of different industries and project types.
Cons
Expectations are high, which means finding a good work/ life balance can be tricky. There are systems in place to support that (i.e. weekly surveys and facilitated discussions about sustainability with case partners, opportunity to take leaves of absence and "time for you", good protection of vacation time). Still, working hours during a case can be high.
