"The best predictor of your employee's future behaviors is his/her relevant past behaviors." Stephen Robbins
Managers mostly pay attention to people characteristics for recruitment, but actually what matters for them is their behaviors. Characteristics are not good predictors of behaviors. Because:
1) People's behaviors are heavily influenced by environment, specially new and abnormal ones. They may show different behaviors than their characteristics in workplace due to organizational culture and environment.
2) People can adapt their behavior based on the new conditions.
So how can recruiters predict candidates' behaviors as accurate as possible?
As Stephen Robbins said, recruiters should explore candidates' relevant past behaviors and performance. This could be done by using STAR model. Spend most of the interview period asking about situations relevant to the job offer and your organization culture and find out how the candidate reacted to that situation and what the result was.
This kind of structured interview is the best predictor and help you improve your prediction by 63%. To become 100% sure, you need a proper and mature onboarding process.
