Perhaps attitude might make more sense then personality, as your personality can change over time/environment. Environment affects a lot of personality and how it's perceived, and expressed. A toxic workplace will make a lot of difference but people with more healthy attitudes will likely leave quickly, those with poor views on life or self image will likely stay. This would of course effect training and improving skills.
