The 30-30-30-10 Rule to Talent Selection
Chally encourages clients to consider balanced, multi-phase systems for the most effective candidate selection results. We recommend the “30-30-30-10 Rule” be followed. Thirty percent of a final selection should be based on test results, 30% on background information and reference checks, 30% based on interview results and the final 10% on perceived fit with the company’s culture.
To assist clients in implementing a structured, scorable interview process, Chally offers tailored Interview Evaluations and an Interview Guide
Chally has created Interview Evaluation forms for specific positions with cone questions for each of the critical success skills that have been identified for that particular position. Research has shown the cone question approach is the most effective process for interviewing. When using this approach, the interviewer asks open-ended questions which focus on characteristics sought in the candidate. An alternate set of cone questions for each of the critical success skills is also available so if there is more than one person interviewing a candidate, you will automatically have cone questions for both people responsible for interviewing. Both forms of the evaluation include a rating scale to score answers.
This Guide provides information on basic techniques that can increase confidence in the outcome of the interview process. It covers the key factors that research has shown to be most useful and beneficial when trying to hire the right people.
