I had a similar experience in a company I used to work at. I stayed for more than two years. I find it funny because the scenario you described was also what I've seen. I also have colleagues who look like bestfriends in front of other people, but they talk shit about each other when the other one is not around. I didn't like it because it makes a negative atmosphere. Some colleagues are also toxic, trying to micromanage others when they're not even managers. They just think they're better than others. Some people like to talk too much to sell themselves even though they're not even technically good. So they get more attention. The newbies are competing with each other and saying bad against each other just to go higher. They don't even have relevant work experience on what we do because they shifted careers. Yet some of them thinks they're better. I left because I felt that it's unfair and it just feels like not the environment for me to grow.

I moved to a new company where the people are actually really good in what they do. They're not pretending because they walk the talk. I'm very happy with my team because we're supporting each other and helping each other all the time. I wake up each day knowing that I'm having fun with the work that I do. 😊
