How to choose the right interviewee for your case study

Joe Sherwood Co-Founder

Choosing the Right People for Your Case Study Videos

In a previous blog, we explored how to choose the right clients for your video case studies. But selecting the right client is only half the job. Once that’s done, the next step is just as important — making sure you have the right people sitting in the interview chair.

It’s Not About Who’s Available

When planning a case study video, it can be tempting to go with:

  • The team member who happens to be available on the day
  • The person most comfortable on camera
  • Someone who’s keen to raise their own profile

But this approach can weaken the impact of your video. Instead, your focus should be on choosing the people who can best communicate the message you want your audience to take away.

Focus on Message, Not Convenience

Every case study video has a purpose — whether that’s building trust, demonstrating ROI, or showing real-world impact. The people you interview should be chosen based on how well they can:

  • Explain the problem they faced
  • Share why they chose your product or service
  • Clearly articulate the results and outcomes
  • Bring authenticity and credibility to the story

It’s about aligning the speaker with the story — not just filling a seat.

Why One Perspective Isn’t Always Enough

Often, a single interview won’t tell the full story. That’s where bringing in multiple voices can make a real difference.
For example, you might include:

1. The Decision Maker

Someone responsible for the commercial decision to invest in your product or service. They can speak to:

  • Why they chose your solution
  • The decision-making process
  • The measurable results and return on investment

2. The End User

The people actually using your product or service day-to-day. They can bring the story to life by sharing:

  • How the solution fits into their workflow
  • How it’s made their job easier
  • Time saved or efficiencies gained
  • What they can now do differently as a result

Tell a More Complete Story

By combining these perspectives, you create a richer, more compelling narrative.
You’re not just telling prospects what happened — you’re showing them:

  • The strategic thinking behind the decision
  • The real, human impact on the people using it
  • The tangible and intangible benefits across the business

This layered storytelling builds stronger trust and relatability.

Get More Value From Your Shoot

There’s another big advantage to interviewing multiple people — content versatility. With just a bit more planning, you can create multiple pieces of content from one shoot:

  • A results-focused video – Ideal for decision-makers, highlighting ROI and commercial impact
  • A user-focused video – Perfect for showing internal buy-in and day-to-day benefits
  • Short-form cutdowns – Snippets tailored for social media, ads, or sales follow-ups

This approach helps you maximise your budget and extend the lifespan of your content. Plan Ahead — It Pays Off.
Taking the time to carefully plan who you interview might seem like a small detail, but it has a huge impact on the final result.
The right voices will:

  • Strengthen your message
  • Improve credibility
  • Increase engagement
  • Ultimately drive better results from your video

Final Thought

Whoever is sitting in that chair matters more than you think.
Choose wisely, and your case study videos won’t just tell a story — they’ll sell it.
