How can I effectively manage a “brilliant jerk”?

The answer is boringly simple, but time-consuming and potentially painful for everyone involved:

• Give them positive and negative 🔄Feedback on their behavior
• Observe if they continue the good behaviors and quit the bad ones
• Consider Performance Improvement Plans (PIP) as a last resort in case they keep poisoning your team or the wider organization
• Keep them if they pass their PIP, terminate otherwise
