Ex-McK is right.I am currently working at McKinsey, and ready to leave it, now-ENOUGHToo much politics.I chose it, because I was sold the wrong expectations.As part of one "practice" I was told I would work 9am to 18/19pm at the client site.Friday normally finishing at 4pm. That made a total of about 48 hours/week. (In my industry with 8 hours overtime i coud have made about the some money- But the career progression loooked good)In summary reality has been:1) on engagement you never work less than 75-80 hours/week2) the higher you go, the more you work (it is normal from EM above to work 100 hours/week, and yes, there are regularly people in the london office saturdays and sundays3) I had to take up to 16 flights/month and still expecting to work on the planes4) feedback are as sharp and harsh as a razor blade, leaving you speechless and bleedingso are people happy? Depends who asks the questionMost of them would say to their parents :"NO"But this is a highly political place, and you need to be very very careful of what you say and who you say it to.so they will all say:"YES, I am happy,beautiful"Rewards to make it to partner:at any entry level you will sell your soul to the devil, they will own you and beware of complaining.The upper you go, the more you have to sell.Take a look at a one day in the life of an AP and Parter: it is interesting enough to put on fire all your university books, sell your house and move to the Canaries, selling postcards to the tourists and fishing your own food.You have one life only, man.None will give you a second one. And you will not be the one enjoying your millions...Another bottom line is: 97% of the "normal human beings I interact with"have vague or no idea at all of what McK is or does....
