A personal interview is a type of interview that employs verbal questioning as its principal technique of data collection. It is a face-to-face conversation between the interviewer and the interviewee, where the interviewer asks open-ended or closed-ended questions to obtain information from the interviewee. A personal interview can be conducted in various settings, such as at the interviewee’s workplace, home, or a neutral location. A personal interview can be structured, semi-structured, or unstructured, depending on the level of flexibility and standardization of the questions. A personal interview can be used for different purposes, such as to assess the interviewee’s competence, motivation, attitude, or opinion on a certain topic. A personal interview can also be used to establish rapport, trust, and credibility between the interviewer and the interviewee. A personal interview can have various advantages and disadvantages, such as:

Advantages:

It allows the interviewer to observe the interviewee’s body language, facial expressions, and tone of voice, which can provide additional insights into the interviewee’s feelings, emotions, and reactions.

It enables the interviewer to probe deeper into the interviewee’s responses, clarify ambiguities, and ask follow-up questions to obtain more detailed and comprehensive information.

It gives the interviewer the opportunity to adapt the questions and the pace of the interview according to the interviewee’s level of knowledge, interest, and responsiveness.

It can increase the interviewee’s willingness to participate, cooperate, and disclose information, as the interviewer can establish a personal connection and a positive atmosphere with the interviewee.

It can reduce the possibility of misunderstanding, misinterpretation, or distortion of the information, as the interviewer can verify and confirm the interviewee’s answers immediately.

Disadvantages:

It can be time-consuming, costly, and labor-intensive, as it requires the interviewer to travel to the interviewee’s location, schedule the interview, and conduct the interview.

It can be influenced by various biases, such as the interviewer’s expectations, preferences, stereotypes, or prejudices, which can affect the interviewer’s choice of questions, interpretation of answers, and evaluation of the interviewee.

It can be affected by various factors, such as the interviewer’s skills, personality, appearance, or mood, which can influence the interviewer’s performance, behavior, and interaction with the interviewee.

It can be subject to various errors, such as the interviewer’s memory, recall, or transcription errors, which can result in the loss, omission, or alteration of the information.

It can pose various challenges, such as the interviewer’s difficulty in maintaining control, neutrality, or objectivity, or the interviewee’s reluctance, resistance, or dishonesty, which can hinder the quality and validity of the information.
