Use the STAR Methodology: Structure your responses using the STAR approach (Situation, Task, Action, Result). This helps in providing comprehensive answers and demonstrating your problem-solving process effectively. Engage with the Interviewer: Ask clarifying questions to ensure you understand the context and specifics of what is being asked. This shows your engagement and helps tailor your answers more accurately. After answering, check in with the interviewer by asking if they need further clarification or if they understood your response. This ensures your answers are clear and addresses any follow-up questions they might have.
