5 Tips to Prepare for Any Product Design Interview

1. Google Yourself

Most people go into an interview with the intention of making a great impression – which is the best attitude to have! However, sometimes, the first impression your employer gets is from your online presence. Think about it. If they’ve bothered to google you, even once, your interviewer may have already formed an opinion of you.

So, when was the last time you searched your name online? If you have a product design interview coming up, we highly recommend doing so!

After all, you want the company to get to know you as a designer, so it is important to make sure your online persona represents you well.

2. Show Your Design Process

It almost goes without saying that your portfolio is important! So, what should you show? There’s no right or wrong answer. As a product designer, you can apply design thinking to this task and curate the best possible portfolio.

You’ll want to include your best pieces, of course – creations that undoubtedly speak to your visual design aesthetic. But, what else?

In addition to those high-fidelity portfolio pieces, consider showing your design process as well. Are sketches a part of your process? Do you use stickie notes to brainstorm? Use this opportunity to show off your insightful and dynamic thinking skills!

3. Be Enthusiastic

Going through the product design interview process can be a bit daunting – especially if you have your heart set on the role. However, it is important that you don’t give in to feelings of anxiety. Instead, try to remain enthusiastic!

Enthusiasm is especially important for those who are participating in a phone interview or video conferencing session with their prospective boss. In those instances, verbal cues may be disruptive. But, the good news is that enthusiasm can be shown in other ways! Want to show you’re actively listening? Smile, nod, and acknowledge the interviewer often.

4. Do Your Research

As a product designer, surely you’re familiar with conducting user research. So, apply similar research methods to get to know your soon-to-be boss a little better!

Why? Well, gathering information ahead of time can help you craft a dynamic design presentation and discuss your design process with ease.

5. Actively Listen & Avoid Over-Talking

During the interview process, you’ll likely want to share as much as you can – with the goal of standing out from the other candidates. While this approach can work, it’s important that you strike a balance between listening and responding to your interviewer.

Our advice? Avoid over-talking. You don’t need to share every detail of your last position. Instead, take moments to actively listen and, when appropriate, ask questions about the role you’re applying for.
