went through cloudflare's product designer / UX interview process this spring. sharing because the design interview landscape at infra-focused companies is weird and i didn't find useful signal when i was prepping.
the context. cloudflare design is a small team relative to company size. you're designing for a very technical user base: developers, security engineers, network admins. that context shapes everything about how they evaluate you.
the process. recruiter screen, then a portfolio review + 45-min conversation, then a design challenge (take-home, one week), then a final round with 3 people.
portfolio review. they asked me to walk through 2-3 projects, targeting ones relevant to developer tooling or technical products. they pushed hard on the problem framing stage, not just the solution. questions like: how did you define the problem before designing anything? what did you learn from users that changed your initial direction? how did you scope what you wouldn't solve?
they did not care much about visual craft for its own sake. they cared about whether you had a point of view and could explain it.
take-home design challenge. they gave me a specific scenario involving a Cloudflare Workers dashboard feature. one week. my output was a figma file + 2-page written rationale. the written rationale mattered as much as the designs themselves. they want to see that you can articulate constraints and trade-offs.
final round. three conversations back to back: one with a product manager (all about prioritization and how you work with PMs), one with an engineer (they'll poke at technical feasibility of your designs, be prepared to defend), one with the design manager (culture, values, career ambitions).
a few things i'd highlight: know cloudflare's product surface at least at a high level. dashboard.cloudflare.com is worth spending time in. be ready to talk about designing for density and information architecture, not just pretty screens. their users want data, not delight. they asked about accessibility explicitly. not just 'did you consider it' but 'walk me through how you'd validate contrast ratios and keyboard navigation in your design system'.
i came out of it with an offer for a senior product designer role. the team seems solid and the work is genuinely interesting if you like complex technical products.
