Larvol Group has a corrupt management culture, mostly dictated by Bruno himself but all the bosses perpetuate it. They are offensively cavalier about screwing with peoples' compensation. Whenever Bruno decides it's more efficient for some group to be on a different pay structure, they're all required to sign a new employment contract or they're out the door. Your new contract will of course not include all the concessions they pretended to make when negotiating your previous contract.
For anyone who isn't at the very bottom of the company, they promise a big paycheck then at the last moment reveal that you only actually make half of that, and the other half is in the form of a completely discretionary "flexible bonus" which you won't get much of. They give various excuses about the bonus, like "smaller bonuses across the board this year because the company made less money than expected" right before sending the yearly update bragging about how well the company is doing financially.
The review process is designed to be extremely competitive, they copied all the techniques used at Amazon where everyone is ranked against each other and it determines your bonus. There is zero politeness around this, all year long your boss will threaten you financially, speaking very plainly about how your bonus will be lower unless you work extra hours etc.
The day to day management procedures are more intrusive than anywhere else I've ever worked and you will waste lots of overhead time creating daily reports of the time you spent, and being in daily meetings with your boss where they grill you about your time report, demanding more detail about every point, but also incredulously challenging every detail you give them. You will drive yourself mad trying to determine the level of reporting granularity which minimizes how much your boss complains at you (there isn't one). What they really want, but won't actually say, is for you to work more than you are reporting.
