Unfortunately, you are unlikely to know who is a truly nice person and who is a backstabbing true believer. The atmosphere is one of constant paranoia. You never know whether what you're saying will be used against you---the gossip train is malicious. In fact, just talking to people in other departments will earn you a slap on the wrist or worse, and don't even think about trying to improve anything or have an honest conversation about your challenges. At best you'll get a "just a reminder" email directing you to documentation on the server with the implication that you'll just ... learn how to get your job done all by yourself, even when expectations are unclear and the job is literally impossible. I have heard stories of people staying late at night or working all-nighters on holidays. At worst, you'll be branded an outsider and possibly suffer major consequences.
Previous reviews have detailed the total lack of training and expectations. 6 months after being hired I still had no idea how ebooks were made and how publishing worked, and had to piece together what I could based on overhearing conversations and my own detective work. Noises about managers /thinking/ about training me were made but none were followed through on. "Feedback" was given FIVE MONTHS after being hired, in the same "just a reminder" format. I frequently heard tech team members pointedly wondering aloud what basic publishing terms meant. Although experts were within earshot, they simply didn't respond because other departments seemingly didn't concern them. Or, as always, everyone was expected to learn everything from scratch by themselves.
Everything about this company is a farce and a lie: they don't want input, they don't want teamwork, the schedule is not flexible, there is no spirit of collaboration. Certain departments get a say, others don't. Managers are dramatically out of touch with their teams: they were hired when the company started and are treated differently from the rote assembly line workers. Senior staff don't listen to employees, or even allow them to raise their concerns. Feedback disappears into a black hole of process that seems to purposely exclude and demean junior employees. Even when a few simple changes would make a team's workday incredibly more efficient, it's clear that priorities are elsewhere, but this isn't explained.
They don't care about their employees. They just want your head down and your work done. More work, of course, than anyone can reasonably do in an 8-hour day.
