McKinsey/Bain in Korea?

-as mentioned by kidflash hours are intense at most/all consulting firms in Korea

-Fluent/near native Korean is required and at least business level English (unless you're relatively senior and transferred from another office). your interviews, including case, will be done in Korean.

-almost all staffing is done domestically, though experienced consultants get staffed on out of region cases if they have some expertise (e.g., they built up an expertise in a technology or process that they worked on for a Korean client and a client in another region is looking to do something similar)

-not sure what level you are thinking about (analyst vs. associate) but most of the Korean analysts that did undergrad in Korea basically graduated from 4 schools (SKY + KAIST). at the associate level they hire from all the top b-schools but also have a large number of APD (generally PhDs, typical profile of these folks being undergrad at SNU/KAIST, a stint somewhere like Samsung Electronics, and also a PhD at somewhere like MIT, Stanford, etc...)

-my sense is that analysts coming out of a place like Mck, Bain, etc.. in Seoul have pretty good options--going to industry, going finance, tech, etc...last I heard the pay in the Seoul office at the analyst level is lower than the US so sometimes moving from consulting to another industry, the pay is not an issue and in some situations the pay may be pretty similar or even a step-up

-on the other hand, at the associate level, working in one of these places up or out + lack of great exit options in Korea can make it a very competitive place to work. for many at the associate level and beyond moving to industry usually leads to making less working for a company that is not so great and not much/if any decrease in hours worked. there are exceptions, such as folks that stick it out and make principal and then end up joining a Korean corporate at very senior level...there'a lot of pain in that path though.

-while over the last few years Seoul offices of well-known US consulting firms have been busy, my understanding that even as recent as early as this year incoming business had slowed for places likes McK due to a combination of different reasons: more internal strategy teams at the large Korean companies, more competition from other consulting firms (domestic firms and new foreign entrants) that opened offices that may do the same work as a McK/Bain for cheaper (in the case of domestic firms, many of the senior consultants are former McK, Monitor, Bain, etc..), and just the general fact that even the largest Korean companies are pretty cheap and hate paying fees to service providers (lawyers, banks, consultants, etc...), which is further amplified by the unstable economic climate of the last few years

hope that helps.
