If you watched Wolf of Wall Street and you thought DiCapprio was someone to look up to, you'd fit in at a 3G company. It's the worship of financial gain at all costs. Don't be fooled by things like 30% bonus at manager level, and up from there. You'll get a list of ridiculous goals. Whether you "achieve" them depends 100% on how much they like you at the moment (been here <2 years = they like you. After that, "bad cultural fit.") and on whether a VP has the same goal. If a VP has the same goal, life is great, cause the definition of the goal will magically alter through the year to make sure it's achieved. Otherwise, good luck.
Another fun thing is the company bases its primary financial goal each year on EBITDA, but internally-defined EBITDA. Each year, the board ends up approving a giant "restructuring" amount that doesn't count towards that internal EBITDA. So then they fire a ton of people and put the entire salary for the year into that restructuring pool. When numbers are down,the axe starts making the rounds, so the VPs can get their bonuses. These people would fire their own children to make sure they get their bonuses. Using EBITDA also means capital expenditures never hit it. Want to learn about GAAP? Work at BK. You'll learn every possible way to make an expense, especially labor, capitalizable.
Everyone says there's zero work-life balance, and everyone is right. You are considered a bad cultural fit for any number of reasons they make up (it's the catch all reason for firing someone or the excuse when someone quits), but the best way to get that distinction is to leave the office at a reasonable hour.
Upper management consists of the survivors. The people who felt they had to get ahead by just staying all those late hours and stealing credit from the people who can get jobs elsewhere and so felt they could go home. There are some good people in upper management, but they're far outnumbered by people who don't have any sort of specialization, but read a 60 page book about "One Minute Management" and think they're brilliant. "I'm a VP. I must be really good." No, you were mostly in the right place at the right time, when 3G showed up and fired 75% of the company, then replaced them with fresh grads.
It should be telling that upper management routinely has a talent retainment goal.
