Company too large and unmanageable.
Driven by greed above all else, not by customer service (they fake customer service just for money reasons, not because they truly care about the customer)
Abusive team whereby the best performers like me in my case get punished by bad treatment by team members who are underperforming and jealous (I was delivering more than 4 other senior people, and instead of rewarding me with complements and asking me what my secret was, they all turned against me)
No management protection of excellent performers against bad performers who haven't delivered in several months. They seem to emotionally prefer bad performers just because they have been at the company a long time and are "sensitive" while not giving any good treatment to new excellent performers despite them having "sensitive" feelings too. Why not care for their sensitive feelings equally? It's a double-standard and discrimination.
HR doesn't care at all about maltreatment by other employees. The HR lady yelled at me very rudely in the exit interview claiming that despite my excellent performance "I was not a good fit for the team" without giving any reasons and ignoring the fact that teammates were all rude and wouldn't give me the entitled respect for my performance by asking me for my secret sauce of excellence to teach them to rise up to my level. HR instead worried about the feelings of bad mediocre underperformers who were jealous of excellent performers like me (apparently they've done that against other people in the past too, not just me).
Teammates stab in the back and have no honor whatsoever.
Management is weak and mushy as it is unable to hold the bad teammates accountable for maltreating their coworkers, yet they "worry about the feelings" of the bad employees who are the true bullies while discriminating against the one or few employees who are performing well and getting mistreated, including their feelings being hurt.
