Aspirants can handle unexpected questions in interviews by employing specific strategies. First, maintaining calmness and a composed demeanor is pivotal, as it helps in thinking clearly. They should take a moment to reflect on the question before responding. Practicing mock interviews can also familiarize candidates with varying kinds of questions, reducing anxiety. Additionally, using the STAR method (Situation, Task, Action, Result) helps structure responses succinctly. It’s also beneficial to connect unexpected questions back to core values or experiences, allowing for a compelling narrative that demonstrates character and resilience.
