Absolutely everything. The top management is toxic and therapy is long overdue for them. They talk to people humiliating their every word and step.
There are 80% people are getting fired without being compensated.
Also, what is pretended to be an "innovative" company track working tasks in hundreds of word documents. Not a single project management tool. You can be assigned with a task within those hundred of documents and you'd never know because it's no notifications. This alone could be the reason to be fired.
Furthermore, most of employees are Ukrainian people in immigration. And it's the hiring strategy, so people have to choose to leave it. But again, it's not guaranteed that you'll be paid off in the end of the month.
