Preparation for an Investigative Interview

Before conducting an investigative interview, it is crucial to adequately prepare in order to increase the chances of obtaining valuable information. Here are some key steps to take during the preparation phase:

Research and Background Information

Gathering as much information as possible about the interviewee and the case at hand is essential for a successful interview. This includes reviewing any relevant documents, reports, or evidence related to the investigation. Additionally, conducting background research on the interviewee’s personal and professional history can help in developing targeted questions and strategies.

Setting Up the Interview Room

The physical environment in which the interview takes place can have a significant impact on the outcome. It is important to choose a location that is private, quiet, and free from distractions. The room should be comfortable and conducive to open communication. Setting up recording equipment, if necessary, should also be done prior to the interview.

Developing an Interview Strategy

Having a clear plan for how the interview will be conducted is essential. This includes deciding on the structure of the interview, the types of questions to ask, and the overall approach to take. It is important to consider the interviewee’s demeanor, communication style, and potential vulnerabilities when developing the strategy. Additionally, preparing for potential challenges or obstacles that may arise during the interview can help in maintaining control and steering the conversation in the desired direction.

Conducting the Investigative Interview

When conducting an investigative interview, it is crucial to establish a rapport with the interviewee in order to gather reliable information. This can be achieved through asking open-ended questions and employing active listening techniques.

Building Rapport with the Interviewee

Building rapport with the interviewee is essential for gaining their trust and cooperation. This can be achieved by establishing a friendly and non-threatening demeanor, making eye contact, and showing empathy towards the interviewee’s situation. It is important to create a comfortable environment for the interviewee to feel at ease and more willing to share information.

Asking Open-Ended Questions

Open-ended questions encourage the interviewee to provide detailed and descriptive responses, rather than simple yes or no answers. By asking questions such as "Can you tell me more about what happened?" or "How did you feel during that situation?", the interviewer can gather more in-depth information and uncover important details that may have otherwise been overlooked.

Active Listening Techniques

Active listening involves fully engaging with the interviewee, focusing on their responses, and demonstrating that you are attentive and interested in what they have to say. This can be achieved by maintaining eye contact, nodding to show understanding, and paraphrasing the interviewee’s responses to show that you are actively listening and processing the information.

By mastering these investigative interviewing techniques, aspiring investigators can enhance their ability to gather accurate and reliable information during interviews.

Handling Difficult Situations During an Interview

When conducting investigative interviews, aspiring investigators may encounter difficult situations that require special techniques to navigate effectively. It is crucial for interviewers to be prepared for various scenarios and have strategies in place to handle them professionally.

Dealing with Hostile or Uncooperative Interviewees

Hostile or uncooperative interviewees can pose a particular challenge during investigative interviews. In such situations, it is important for investigators to remain calm and composed, maintaining a professional demeanor at all times. Building rapport with the interviewee, actively listening to their concerns, and showing empathy can help defuse tension and encourage cooperation.

Managing Emotional Subjects

Interviewing emotional subjects can be delicate, as their emotional state may influence the information they provide. It is essential for investigators to approach emotional subjects with sensitivity and compassion, acknowledging their feelings and creating a safe space for them to express themselves. Validating their emotions and offering support can help establish trust and facilitate open communication.

Addressing Deception and Truthfulness

Detecting deception and assessing the truthfulness of interviewees is a critical aspect of investigative interviewing. Investigators should be trained in recognizing verbal and nonverbal cues that may indicate deception, such as inconsistencies in the interviewee’s story, evasive responses, or body language indicators. Techniques such as asking open-ended questions, probing for details, and observing behavioral cues can help uncover deception and elicit truthful information.

In conclusion, handling difficult situations during investigative interviews requires a combination of empathy, professionalism, and strategic communication techniques. By being prepared for various scenarios and adapting their approach accordingly, aspiring investigators can effectively navigate challenging situations and gather valuable information for their investigations.


In conclusion, mastering investigative interviewing techniques is essential for aspiring investigators to effectively gather information and uncover the truth. By utilizing the strategies and tips outlined in this guide, investigators can enhance their questioning skills, build rapport with interviewees, and ultimately achieve successful outcomes in their investigations.
