Kontras
Your job experience depends mostly on your direct manager. I left after a short period of time. (1) Culture. Culture. Culture. Mid-management expects you to follow their instructions on any technical specs and not deviate from it even if it's potentially solved in a better way. Feedback isn't transparent and instead, employees are terrified of communicating to managers what's wrong and where they need help. My relationship with my manager was combative from day one: whether it was rhetorical questions like "do you know what X metric means?" in order to tease out if I understood a technical concept tested during the interview, or the manager's tendency to associate minor formatting issues of a presentation or chart as a proxy for technical competency (when communication issues were rife), this place needs a shake up.
