Be on the lookout for warning signs in interviews: bad-mouthing past employers (“My last manager was terrible”); blaming failures they were associated with on others (“The reason my last project didn’t succeed was because of internal politics”); insulting other groups of people (“The sales team were bozos”); asking what the company can do for them instead of the reverse (“This feels like a step up for my career”); and coming across with high arrogance or low self-awareness (“I was attracted to this position because it seems like you need someone really senior”).
