How to Prepare for an Expert Interview: A Step-by-Step Guide

Speaking with the right expert can be one of the most valuable things you do before a major business decision. A single well-run conversation can surface insights that weeks of desk research simply cannot produce.

But "well-run" is the key phrase. An expert's time is limited, and so is yours. Walk into the conversation underprepared and you'll leave with vague answers, missed opportunities, and a nagging feeling that you didn't quite get what you needed.

The good news is that preparation is a skill you can build. Here's how to approach an expert interview so you get the most out of every conversation.

Step 1: Get Clear on What You Actually Need to Know

Before you think about questions, think about decisions. What is the business decision this interview is meant to inform? What would you do differently depending on what you hear?

This sounds obvious, but it's where most interview preparation goes wrong. Teams often go into expert conversations with a broad topic rather than a focused objective, and end up with interesting information that doesn't actually move anything forward.

A useful way to sharpen your focus is to write down the two or three things that, if you learned them in this conversation, would make it a success. These become the backbone of your interview guide.

For example, if you're evaluating a market entry into Southeast Asia, your objective isn't simply "learn about the market." It might be: understand the key regulatory barriers for our product category in Indonesia, identify which distribution models are working for comparable businesses, and get a read on how consumer trust is built in this segment.

Specific objectives lead to specific, useful answers.

Step 2: Choose the Right Type of Expert

Not all experts are equal for every question. The type of insight you need should determine who you speak with.

If your questions are strategic, you want someone who has operated at a senior level in your target market or industry. They can speak to competitive dynamics, regulatory trends, and the broader forces shaping the landscape.

If your questions are operational, you want someone closer to the ground: a practitioner who has actually run the processes, managed the teams, or navigated the systems you're asking about. They can tell you what works in practice, not just in theory.

In APAC, this distinction matters even more because local context is everything. A senior executive who ran a business in Singapore may have limited visibility into how things actually work in, say, regional Indonesia or rural India. Be specific about the experience profile you need, and make sure the expert's background genuinely matches your questions before the call begins.

Step 3: Do Your Background Research

An expert interview is not the place to ask questions you could have answered yourself. Going in without basic knowledge of the topic wastes the expert's time and signals that you haven't taken the engagement seriously.

Before the conversation, spend time understanding the fundamentals: the market landscape, the key players, the recent regulatory or industry developments, and any publicly available data relevant to your questions. Read recent news, industry reports, and any relevant company or sector publications.

This preparation serves two purposes. First, it means you can have a more substantive conversation and ask sharper follow-up questions. Second, it gives you a reference point to test what the expert tells you. When you already know the publicly available view, you're better placed to identify where the expert's perspective adds something new.

Step 4: Build Your Interview Guide

An interview guide is not a rigid script. It's a structured set of questions and themes that keeps the conversation focused and ensures you cover the ground you need to, even if the discussion takes unexpected turns.

A good interview guide for a 60-minute conversation typically includes:

A brief opening section where you introduce the context and your objectives. This helps the expert understand what kind of input would be most useful, and it invites them into the conversation as a genuine collaborator rather than a question-answering machine.

Four to six core question areas, each with a primary question and two or three follow-up prompts in case the expert's answer is brief or misses the point you were after.

A closing question that invites the expert to share anything you haven't thought to ask. Some of the most valuable insights come from this final, open invitation.

Keep questions open-ended. "How has distributor behaviour changed in Vietnam over the past two years?" will give you far more to work with than "Has distributor behaviour changed in Vietnam?"

Send the guide to your expert in advance. It allows them to prepare more useful responses and signals that you're a thoughtful, organised client worth engaging with seriously.

Step 5: Prepare Your Team

If more than one person will be on the call, assign roles before you start. One person should lead the interview and manage the flow of the conversation. Others should focus on taking notes, tracking which questions have been covered, and flagging anything they want to follow up on.

A common mistake in team interviews is everyone jumping in with questions at once, which can feel disjointed for the expert and make it harder to pursue a line of thinking in depth. Agree in advance on a signal for when someone wants to add a question, and keep the lead interviewer in control of the pace.

If you're operating across time zones, as is often the case in APAC, confirm the time, dial-in details, and any technical requirements well ahead of the call. A late start or a technical problem eats into your interview time and unsettles the conversation before it has begun.

Step 6: Be Ready to Listen, Not Just Question

The best expert interviewers are active listeners. They follow the thread of what the expert is saying, pick up on details worth exploring further, and resist the urge to jump to the next question on their list the moment there's a pause.

Go in with your guide, but hold it loosely. If the expert says something surprising or raises a point you hadn't considered, follow it. That unplanned direction is often where the most valuable insight lives.

Aim for the expert to be speaking around 80% of the time. Your job is to guide the conversation, not to fill it.

Step 7: Capture and Consolidate Quickly

The value of an expert interview degrades quickly if you don't capture it properly. Write up your notes as soon as possible after the call, ideally within the same day while the context is still fresh.

Note not just what was said, but what it means for your decision. Where did the expert's view confirm your existing assumptions? Where did it challenge them? What follow-up questions does it raise, and is there another expert you should speak with as a result?

Over the course of multiple interviews, you'll start to see patterns emerge. Consistent themes across different experts carry significant weight. Points of disagreement between experts are equally valuable: they often point to genuine uncertainty or complexity in the market that deserves further investigation.

The Difference Preparation Makes

A well-prepared expert interview does more than surface useful information. It builds the kind of nuanced, ground-level understanding that shapes genuinely better decisions.

In a region as complex and fast-moving as Asia Pacific, that kind of human insight is often the difference between entering a market confidently and finding out what you should have known only after you've committed.
