Describe the setting.
Competency based questions are interview questions that require you to provide real-life examples as the basis of your answers. The interviewer is looking for you to explain why you made certain decisions, how you or your team implemented these decisions and why certain outcomes took place.
Competency-based interviews (also called structured interviews) are interviews where each question is designed to test one or more specific skills. The answer is then matched against criteria and marked accordingly. For example, the interviewers may want to test the candidate's ability to deal with stress by asking first how the candidate generally handles stress and then asking the candidate to provide an example of a situation where he worked under pressure.
Interviewers using behaviour-based interviewing techniques such as competency questions are likely to ask for additional details during your responses. Always make sure you provide concise, specific answers that are well explained, thought out and detailed.
Questions can relate to past failures as well as to past achievements. You must adequately explain why you failed to complete tasks; when such questions are posed, don't avoid mention of past failures altogether, but demonstrate what you have learnt from them.
If you find yourself struggling to think of any prior experiences which are relevant to the question asked, give a hypothetical answer and describe what you would do if a similar situation were to occur in the future.
You can use the STAR technique to help structure your answers for competency questions. The diagram on page 2 explains how what the interviewer is looking for in your answers.
Describe the setting.
Describe what task was required of you.
Tell the interviewer what action you took.
Conclude by describing the result of your action.
Be positive about your actions throughout your response and do not make up an example as you will not come across as believable. If you cannot think of good examples instantly, ask the interviewer for a moment or two to think about the question and then give your answer.
