Preparing for an Investigative Interview

Understanding Your Subject

Every investigative interview begins long before the recorder is turned on. The foundation of a productive conversation is a thorough understanding of the person sitting across from you, the topic under discussion and the broader context that connects them. Whether you are interviewing a whistleblower, a public official or an industry expert, the depth of your preparation directly determines the quality of the material you will gather.

Start by mapping out everything that is publicly available about your subject. Court filings, corporate registries, published interviews, social media activity and professional affiliations all contribute to a profile that guides your approach. In Canada, resources such as the Federal Corporations database, provincial land registries and the SEDAR+ system for securities filings are freely accessible and frequently reveal connections that are not immediately obvious.

The goal is not to confront or entrap. It is to arrive at the interview with enough context to ask precise questions and to recognize when an answer is incomplete, evasive or contradictory. Preparation protects both the journalist and the source: it reduces the chance of wasting time on ground already covered and signals to the interviewee that you take the subject seriously.

Building a Source Strategy

Investigative work rarely depends on a single source. Before you schedule your primary interview, identify the surrounding network of people who can provide corroboration, context or alternative perspectives. A source strategy is a deliberate plan for the order in which you approach people, the information you share with each and the protections you offer.

Consider the following when mapping your sources:

• Which individuals have direct, first-hand knowledge of the events or decisions you are investigating?
• Who can provide documentary evidence such as emails, contracts, internal memos or financial records?
• Are there former employees, competitors or regulators who may speak more freely than current insiders?
• What is the risk profile for each source, and what level of anonymity or protection is appropriate?

Approach peripheral sources first. They help you build a factual foundation and test your working hypothesis before you sit down with the central figure. By the time you reach the primary interview, your questions should reflect a command of the facts that encourages candour and discourages deflection.

Crafting Your Question List

A well-structured question list is not a script. It is a roadmap that ensures you cover every essential point while remaining flexible enough to follow unexpected leads. Organize your questions in thematic blocks rather than a rigid sequence, and mark the three or four questions that are absolutely essential, the ones you cannot leave the room without asking.

Begin with open-ended questions that allow the subject to speak freely and establish a baseline of how they communicate. Move toward more specific, evidence-based questions as the conversation progresses. Save confrontational or document-based questions for the second half of the interview, after rapport has been established and the subject is engaged.

Keep a separate list of follow-up prompts for common evasion patterns. Phrases like "Can you walk me through that step by step?" or "What specifically did you see or hear?" are useful for pulling a vague answer into concrete territory. Avoid compound questions that give the subject an easy exit by answering only the simpler half.

Setting Up the Recording Environment

The technical quality of your recording affects everything downstream, from transcription accuracy to the credibility of quoted material. Whether you are recording in a professional studio or a borrowed conference room, a few practical steps make a significant difference.

At Seideldexa, our 12 m2 soundproofed recording booth is purpose-built for interview work. The enclosed space eliminates ambient noise, and dedicated equipment ensures consistent audio levels. However, many investigative interviews happen in the field, and the principles remain the same regardless of the setting.

Before the interview, verify the following:

• Primary and backup recording devices are charged and tested with fresh storage media.
• Microphone placement captures both voices clearly without requiring adjustment mid-conversation.
• Background noise sources such as air conditioning, traffic or electronic hum have been minimized.
• The recording format is uncompressed or high-bitrate to preserve clarity for transcription.
• A visible or audible slate at the beginning of the recording identifies the date, participants and project.

Always inform the interviewee that you are recording and obtain their consent before pressing the button. In Ontario and across Canada, single-party consent is legally sufficient for recording a private conversation you are part of, but professional ethics and source trust demand transparency.

Managing Sensitive Conversations

Investigative interviews frequently involve material that is personally, legally or politically sensitive. The way you handle these moments determines not only the quality of the information you receive but also the safety and well-being of your source.

Establish ground rules at the beginning. Clarify whether the conversation is on the record, on background or off the record, and ensure both parties share the same understanding of those terms. Canadian journalism conventions align broadly with international practice, but it is worth stating your definitions explicitly to avoid misunderstanding.

When a source becomes visibly uncomfortable, pause. Acknowledge the difficulty of the subject without pressuring them to continue. Offer to revisit the topic later in the conversation or in a follow-up session. Pushing too hard at a delicate moment can shut down the entire interview and damage a relationship you may need to maintain for weeks or months.

For sources who face genuine risk, whether professional retaliation, legal liability or physical safety, discuss your source protection protocols in advance. Explain how you store recordings, who has access to notes and under what circumstances you would resist a legal demand for disclosure.

Legal and Ethical Boundaries

Canadian law provides certain protections for journalistic work, but those protections have limits that every interviewer must understand. The Journalistic Sources Protection Act (S.C. 2017, c. 22) establishes a qualified privilege for journalists to protect the identity of confidential sources, but this privilege can be overridden by a court order if the information is essential to a legal proceeding and cannot be obtained by other means.

Beyond legal requirements, ethical obligations shape how you conduct an interview. The Canadian Association of Journalists Ethics Guidelines emphasize accuracy, fairness, independence and accountability. In practice, this means:

• Never misrepresent your identity or the purpose of the interview.
• Do not promise outcomes you cannot guarantee, such as absolute anonymity or editorial approval.
• Distinguish clearly between facts the source provides and opinions they express.
• Give the subject of an investigation a fair opportunity to respond to allegations before publication.

If your investigation touches on matters that could result in defamation claims, consult a media lawyer before publication. The cost of a pre-publication legal review is a fraction of the cost of defending a lawsuit, and it is a standard line item in any well-planned investigative budget. For guidance on budgeting for legal review, see our guide on budgeting for journalism projects.

After the Interview

The work does not end when the recorder stops. Post-interview tasks are as important as the preparation that preceded the conversation, and they should be completed promptly while details are fresh.

Begin with a full transcription of the recording. Automated transcription tools can produce a rough draft quickly, but human review is essential for accuracy, especially with names, technical terms and passages where audio quality is uneven. Time-stamp key sections so you can locate critical quotes rapidly during the writing phase.

Next, verify every factual claim the source made against independent evidence. Cross-reference dates, figures, names and events with documentary sources. Where the source's account diverges from the record, note the discrepancy and plan follow-up questions or additional sourcing.

Finally, assess whether the interview changes your working hypothesis. Strong investigative work is willing to follow the evidence wherever it leads, even if that means abandoning an initial angle. Update your source map, revise your question list for remaining interviews and document any new leads that emerged.

If your investigation will produce audio or multimedia content, consider which format best serves the story. Our guide on choosing the right format for your story covers the decision-making process in detail.
