To approach interviews with confidence and clarity, candidates should engage in thorough preparation and practice. Mock interviews can simulate the real experience, enabling candidates to articulate their thoughts effectively. It is essential to be well-versed in current affairs, personal achievements, and the service profile. Practicing body language and maintaining a positive demeanor enhances presentation. Furthermore, framing responses using structured approaches like the STAR method (Situation, Task, Action, Result) can provide clarity. Lastly, staying calm and composed allows candidates to think clearly and respond confidently during the interview.
