Everything else. Management will take you for a spin. They tell you to ask questions, but lose patience with you if you do. If you try to do it yourself and get it wrong, they call you out for not asking questions.
They encourage you to "do things your way" but won't hesitate to micromanage you even if you achieve the desired result; from the way you speak on the phone to how you draft emails or use their software. Also, most of them speak in broken or heavily accented English, so communication can be tough.
At first, the employees seem "friendly" but they are actually just disconnected. They don't confront you not because they're nice but because they don't really care about you, meaning there is no unity here unless you are part of the established cliques.
I spoke with different departments due to my role and everyone is the same: hostile and unsupportive. The rare supportive ones lose patience. It almost seems like each department is a different hydra head and are only looking out for themselves.
The management needs a serious overhaul. They are great at producing results for the CEOs, but horrible in integrating new employees. The CEOs are ghosts, you'll never see them. HR doesn't help but it's not their fault since the problem is that management is rotten at the roots. Many of them were here for decades already, so it's hard to change the status quo and their old way of doing things.
To be fair, if you somehow join and are BY DEFAULT the type of employee they want and you already have the skills, then the benefits and pay are actually quite nice. That's just it though, this is their hiring style. They will not nurture you, there is no (adequete) training, and if you fall down they will not help you up. You will just fall and fall and fall until they decide to push you to quit so they don't pay unemployment.
In summary, the work environment is cutthroat and sometimes toxic. They are stubborn and cling to old ways of doing things, it is not a modern-style office. Management is good at producing results but horrible at helping new employees. There is poor training and nobody cares about you unless you already produce results. If you have the personality and skill right out the box, then I can see the job being decent for a few years. Otherwise, save yourself the headache. I plan to leave after covid passes myself.
