  • 3For creative roles prioritize the portfolio; for product/leadership roles prioritize a tailored cover letter that references 1–2 portfolio artifacts.
  • 4Always link the cover letter to specific portfolio case studies and curate work to match the job description.

Conclusion

Frequently Asked Questions

It depends on the role. Creative and technical roles almost always expect a portfolio, while product, marketing, and leadership roles value a targeted cover letter that explains fit. When possible, provide both and make sure they reference each other.
Aim for 400–800 words per detailed case study with visuals and metrics. Keep the one-line summary under 20 words and include clear headings (Problem, Process, Solution, Impact). For a quick portfolio, 3–6 strong case studies are ideal.
You can use a template, but always customize at least 2–3 elements: the company name, the specific problem you’ll solve, and one relevant metric or example. Generic letters typically perform poorly with hiring managers and ATS systems.
If you lack hard metrics, provide qualitative outcomes (user quotes, stakeholder approvals, awards) and contextual estimates (e.g., “reduced support requests by ~15%”). Include process insights and what you learned to show growth and strategic thinking.
