Maybe this is late to write regarding your question, but at least this discussion might be useful for others searching for the same topic. Although I have observed all the comments regarding your question, I am still confused about the main part of the question, which is: is there any difference between competency-based and behavior-based interviews?
Difference Between Competency-Based and Behavior-Based Interviews
Yes, there is a significant difference between these two types of interviews. Let me briefly explain:
• In a competency-based interview, the recruiter is trying to identify the core competencies necessary to differentiate high performers from slow performers. These core competencies are reflected in the competency matrix of the position.
• Thus, in a competency-based interview, we are trying to identify what the candidate will perform in a specific situation that may occur in the future, to assess their performance potential.
• In a behavioral interview, the recruiter is trying to identify what the candidate did in the past in specific circumstances to understand their actions and results.
Nevertheless, regarding your senior management's concern that there is a probability a person might fabricate a story and present it to the panel members, it's not a solid reason, and it's not possible. In a competency-based interview, the panel will have many probing questions, such as:
• Please tell me a situation where your communication skills made a difference in senior management decisions.
• What have you learned from this action?
• If you want to perform the same action in the future, what changes will you bring to your action?
• In your point of view, is there any other way to achieve a better result in this case?
However, selection techniques are changing day by day due to the needs of the market and organizations. Please study as much as possible about this question, and do not hesitate to contact me if you have any questions at [Email Removed For Privacy Reasons].
