To articulate thoughts clearly during interviews, candidates can use preparation techniques such as practicing mock interviews and utilizing the STAR method (Situation, Task, Action, Result) for structured responses. Regularly recording speeches and reviewing them fosters self-reflection and improvement. Keeping current affairs in mind while relating personal experiences can make responses impactful. Moreover, engaging in discussions with peers on relevant topics boosts confidence and preparedness. Being clear about one's values and opinions ensures that candidates convey their thoughts systematically and confidently during actual interviews.
