Top 30 Most Common Competency Based Interview Questions You Should Prepare For
Written by
James Miller, Career Coach
Landing your dream job often involves navigating various interview formats. Among the most revealing are competency based interview questions. These aren't just about what you've done, but how you did it, delving into your skills, behaviors, and personal attributes. Preparing for competency based interview questions is crucial because they provide interviewers with concrete examples of your past performance, which is often the best predictor of future success. Unlike hypothetical scenarios, these questions require you to draw upon real-life experiences, demonstrating your capabilities through action and results. Mastering your approach to competency based interview questions allows you to showcase your strengths effectively and confidently. This guide covers 30 common competency based interview questions, offering insights into why they're asked, how to structure your answers, and brief example responses to help you prepare. Understanding the structure and intent behind competency based interview questions will significantly boost your interview performance.
What Are Competency Based Interview Questions?
Competency based interview questions, often called behavioral interview questions, are designed to assess specific skills, behaviors, and attributes required for a role. They operate on the principle that past behavior is the best predictor of future performance. Instead of asking hypothetical questions like "How would you handle a difficult client?", competency based interview questions frame the inquiry around your actual experiences: "Tell me about a time you dealt with a difficult client." These questions target core competencies relevant to the job, such as leadership, teamwork, problem-solving, communication, and adaptability. By asking for specific examples, interviewers gain insight into how you've applied these skills in real-world situations. Preparing for competency based interview questions involves reflecting on your professional history to identify situations that demonstrate the desired competencies.
Why Do Interviewers Ask Competency Based Interview Questions?
Interviewers use competency based interview questions because they provide objective evidence of your skills and abilities. Responding to these questions requires you to provide specific details about a past situation, including the context, the task you needed to complete, the action you took, and the result of your actions (often referred to as the STAR method). This structured approach helps interviewers evaluate not just what you did, but how you approached the challenge, your decision-making process, and the impact of your actions. It moves beyond abstract claims on a resume or cover letter and provides tangible proof of your capabilities. Competency based interview questions offer a more reliable way to assess candidates compared to traditional question formats, helping employers make more informed hiring decisions by seeing how candidates perform under real-world conditions.
