1. Selfishness/laziness
Some people want just a job to pay the bills. They don't identify with it. Or they have other goals. They won't be good at their jobs, only doing the minimum to not get fired.
This is possibly the most common type. It's not necessarily a bad thing. It can be toxic because people who come in wanting to contribute more will be pulled back and ostracized, blamed for working at nights, and so on.
This is probably interviewed and filtered for the most. The best solution is bureaucracy, where they can perform to minimum and everyone is still happy.
2. Defensive
Bullying. Blaming. Sexism. Racism. Most of these are self-defence. The person insisting Indians are bad because they're cheap. The person bad mouthing the framework the seniors use, or juniors' tendency to keep trying new frameworks.
Sometimes it's a fix to a bad culture. Accountability is a cure to laziness, but sometimes some people are given too much accountability. Sometimes goals are too ambitious and teams continually take turns blaming each other to drag out the deadline. Quite often, this blaming is the culture, and consultants may even be brought in to participate.
The fix is usually to calm their insecurities. Bullying, blaming, racism, all seem to drop in less aggressive cultures.
3. Toxic hard work/ambition
Some work hard, and think they need to be rewarded with power, position, money, women. Sometimes they push others down to be higher. Tends to be classist. Some blame others for not working 80 hours/week, for not sacrificing, or for having a family. They wear their divorces like a medal.
These are most likely found in brand name places like FAANG or working for top tier consultants and financial institutions. Many of them aren't that good, as they tend to overwork themselves inefficiently. Some are actually from group 1 but resentful at being forced to work hard.
They tend to be the least filtered group, because many employers/interviewers want someone hardworking. Their real danger is that they tend to get promoted somewhere and burn the place down.
These are the three I'd actively filter out in a personality interview.
There are of course endless lists of toxicity. The inappropriate pervert. Some who score top grades but are too dumb to live (or stay out of prison). Some will resent people who help them. Some think getting paid is dishonest. And so on.
