Because the chosen candidate will help shape the future of the entire company, the selection process for head positions should receive your undivided attention. The individual assessment centre provides first-rate methods to ensure the best candidate is chosen. What makes this procedure highly reliable is the integration of various selection approaches (e.g. interviews, role play) and objective evaluations by independent observers. Our evaluation of the candidate’s performance at an interview can often be biased, as the candidate can impress us with their preparation or our appraisal is skewed by errors such as the halo effect.
