If you’re a snake you go UP the ladder. Prmotion is completely not merit based but based on who you know and if you can get the right management support. If so then you can weather any bad performance and often be promoted. Everyone knows this. So get that right manager support and you’re set for life. PMs can lose a lot of money even if junior and be promoted. It’s well known and it’s great if you’re in that inner circle. Read Reddit and many are calling these inner circle staff members snakes
Svantaggi
Where do I start? A complete and utter mess and HR will not help you in anyway and they too will not follow proper due process and force you out when tasked to by your manager. Do not come if you’re not a scholar as they’re almost guaranteed a path to the top. Do not come especially if mid career as you’re unlikely to last long without the right management support and get terminated for low performance with no justification.
