I was still in the process when I completed a 2-hour take-home style interaction design challenge with detailed instructions. Once I finished and submitted, the next step was a 45-minute portfolio review built around design fit—more than just walking through visuals, it leaned into the deeper reasons behind my decisions, my values in how I approach problems, and how I think in terms of systems.

It felt like the interviewers were trying to understand how I reason end to end, not just whether my screens looked polished. I was surprised by how clearly the “whys” were brought into the conversation during the portfolio portion, and it made the whole round feel more like alignment on thinking style than a traditional critique. I was not offered the role yet, but I left feeling like I’d been able to demonstrate the kind of design process they care about.

I applied and, about two weeks later, I was asked to set aside a couple of hours for an online design assessment on HackerRank. It wasn’t coding, but it was still structured like a timed whiteboard: I had a long prompt to work through and I focused on wireframing and showing my design thinking clearly within the limit. After I submitted, the next step was a recruiter call, and then I moved into a portfolio review where I presented one or two case studies.

The portfolio round was tightly timed and felt pretty straightforward. I had a 45-minute window: I walked through my projects, then there was time for questions at the end. In my experience, the discussion wasn’t just about what I built, but about how I made decisions and how I collaborated—especially details pulled from the decks I shared. The people I spoke with were generally conversational, and when the timeboxes were strict, the interviewers kept things moving.
