When participating in an interview, it is crucial to avoid under-answering questions. To do this, there are a few things you can do. First, make sure you understand the question being asked before answering. If you are uncertain, ask the interviewer to rephrase or clarify the question. Once you understand the question, take a few seconds to gather your thoughts and compose your answer before speaking. When speaking, try to structure your answer in a clear and concise manner. Start with a brief introduction, then provide details and examples to support your response. Avoid rambling or going off on tangents that are not relevant to the question. Aim for answers that are approximately 2-3 minutes long to ensure you are giving enough information without being too verbose. Remember to also pay attention to your body language and tone of voice. Speak clearly and confidently, and make eye contact with the interviewer. By doing so, you convey confidence and competence, which will help you stand out as a strong candidate for the position.
