Bombed google whiteboarding (ux/ui)?

Had my google virtual onsite this week. Think I did pretty well in the interviews except for the whiteboarding challenge. For the prompt I selected, I was really skeptical of why the product (a piece of hardware to facilitate a physical experience) was needed in the first place as opposed to the user just accessing a website/app on their own phone. As a result, I spent a lot of time on the high level, asking questions and trying to get myself to believe in the scenario and forgot to talk about the more tangible aspects of product development like defining success metrics, MVP requirements, technical needs, etc. I did focus on the user but didn't go deep into features so I ended up with a single wireframe vaguely mapping out the main interface screen instead of a multi step interaction. Towards the end, the interviewer asked me where the product can go next. I said something about market expansion but it seemed like he wanted a more imaginative out of the box answer and I couldn't come up with anything. Overall, the entire interview felt more like a free form discovery discussion instead of a structured look at my "process". Any of this sounds like a dealbreaker for them? #design #interviews #ui/ux
