Management consulting is generally considered prestigious (let's define Prestigious as what MBA schools like the most). The top-tier consulting firms are collectively known as MBB, which stands for McKinsey, BCG and Bain. These three companies are the most prestigious management consulting firms to work for. Although MBB firms are clearly the most prestigious consulting firms compared to the big 4 and other companies in the MBB group, the McKinsey brand also outperforms its two competitors by quite a considerable margin.
To a certain extent, this is true: the sector continues to rank as one of the best places to enter as a graduate in the United Kingdom, while some of the best-known consulting firms in the world are considered to be some of the most prestigious workplaces in the world.
