**What are the common mistakes candidates make during UPSC interviews?**
Common mistakes during UPSC interviews include inadequate preparation on vital topics, leading to unsatisfactory answers. Candidates often fail to articulate their thoughts clearly, resulting in confusion. Being overly nervous or exhibiting a lack of confidence can also hinder performance. Responding defensively to questions or appearing disinterested demonstrates unsuitable demeanor. Moreover, not being updated on current affairs or personal biodata may raise red flags. Candidates may also struggle if they don't connect their academic background and interests to the role they aim to achieve. Maintaining a calm composure and effective communication is crucial for success in these interviews.
