An effective interviewer should possess excellent communication skills, both in listening and articulating questions clearly. They must be observant, able to read non-verbal cues, and maintain a neutral and professional demeanor. Empathy is crucial to put candidates at ease, while also being objective and analytical to assess qualifications accurately. Additionally, adaptability is key, as each interview may require different approaches based on the candidate's responses and the job requirements.

Preparation is vital for an interviewer. I start by thoroughly understanding the job description and the company culture. This helps in crafting relevant questions that align with the role. I also review the candidate's resume and any other provided documents to familiarize myself with their background. Creating a list of standardized questions ensures consistency across interviews. Lastly, I ensure the interview environment is conducive, with all necessary materials and technology ready.

Once, I had to interview a candidate who was very nervous, which affected their ability to articulate their thoughts clearly. To handle this, I maintained a calm and reassuring tone, providing reassurances about their qualifications. I asked open-ended questions that allowed them to express themselves more freely. By actively listening and showing empathy, the candidate gradually relaxed, and we were able to have a productive conversation.

To ensure fairness, I adhere to a structured interview format with standardized questions for all candidates. I focus on job-related criteria and avoid personal questions. Using a scoring system helps in objectively evaluating responses. I also take regular breaks to refresh my perspective and avoid fatigue-induced bias. Additionally, I am aware of common biases and consciously work to mitigate their impact during the interview process.

I employ a mix of open-ended and situational questions to encourage candidates to provide detailed responses and share examples from their past experiences. Active listening and follow-up questions based on their answers help delve deeper into their skills and competencies. I also use behavioral interview techniques to predict future performance based on past behavior. Maintaining a non-judgmental and supportive atmosphere encourages candid and informative responses.
