Show reasoning, not just output
Hiring managers can find beautiful screens anywhere. What they cannot assess remotely is judgement. Each case study should explain what you rejected and why.
Three case studies is enough
Depth over breadth. A single well-documented project demonstrates more than a gallery.
The specialisation question
Product design, brand, and design systems are increasingly separate hiring tracks. Positioning as one gets more interviews than positioning as all three.
Common questions
How many projects should a design portfolio have?
Three to five, each with the reasoning shown. More dilutes rather than strengthens.
Do designers need to code?
Not usually, but understanding what is expensive to build is valued and comes up in interviews.
