How to Build an Employer Branding Portfolio

A strong employer branding portfolio is four to six real case studies, each showing a specific brief, your actual role, the approach you took, and a measurable result, built to survive the fact that most of your best work is probably covered by someone else's NDA. The confidentiality problem is the part most candidates get stuck on, and it's the part most portfolio advice skips over entirely.

This guide covers what to include, how to structure each entry, and how to handle client or employer confidentiality properly rather than either oversharing or leaving your best work out entirely.

What to include

Aim for four to six projects rather than a long list of everything you've touched. Each one should be a proper case study, not a screenshot with a caption. For each project, cover:

• The brief: one or two sentences on the actual problem or goal
• The challenge: the real constraints you were working within (budget, timeline, stakeholder resistance, a difficult market)
• Your role: what you specifically owned, separate from what the wider team or agency delivered
• The approach: the reasoning behind your decisions, not just the finished output
• The work itself: the actual creative, campaign, content or programme, wherever you're able to show it
• The result: a measurable outcome wherever you have one to give

If you're earlier in your career and don't have four or five distinct projects yet, one strong internship, placement or single campaign can be expanded into phases (research and positioning, execution, measurement) rather than padded out with weaker, unrelated examples. If you're more senior, be selective: three or four strong, relevant projects beat six mediocre ones, and it's worth tailoring which ones you lead with depending on what the specific role is asking for.

Handling confidential and NDA-covered work

This is the part most portfolio guidance doesn't address, and it matters more in employer branding than in most fields, because so much of the work (EVP research, internal messaging, campaign performance data) is genuinely sensitive to the employer that commissioned it.

The safe baseline is simple: ask first, in writing. Go back to former employers or agency clients and ask permission to include a sanitised version of the work, ideally framed around minimising their risk (no proprietary metrics, no confidential research findings, drafts shared for approval before anything goes public). Don't assume that time passing, or the project no longer being live, makes it acceptable to share without asking.

Where you can't get permission, or haven't asked yet, there are still legitimate ways to represent the work:

Anonymise the client, not the outcome. Replace the company name with a category description ("a global logistics employer," "a Series C fintech scaling headcount fast") and describe what you actually did and why, without naming who it was for.

Be more conservative with numbers than with process. There's a genuine difference of opinion in the source material here worth taking seriously: some guidance suggests you can still cite an anonymised, rounded metric ("open rates improved by roughly 40%"), while more cautious guidance recommends describing the direction of impact only ("meaningfully improved engagement") unless you have explicit permission to share a number. When in doubt, default to the more conservative version and describe your thinking and approach in detail instead. Reviewers are usually more interested in how you diagnosed and solved the problem than in the exact figure anyway.

Recreate rather than expose. For visual or written work you genuinely can't show even anonymised, a recreated example using dummy data or a fictional brand can demonstrate the same skill and process without exposing anything real. Be upfront that it's a recreation if asked.

Never post NDA-covered specifics on public platforms. Anything you wouldn't want a former employer to stumble across shouldn't go on a public portfolio site, however long ago the project ended.

Common mistakes

Showing outputs with no context. A careers-page redesign or a social campaign screenshot means little without the brief, the constraint, and the result attached. Process is usually more persuasive than the artefact alone.

Vague, unquantified claims. "Ran a successful campaign" tells a reviewer nothing. Even a rounded, anonymised figure ("generated several hundred qualified applications on a limited budget") is far more convincing than an adjective.

Overclaiming credit for team output. Be specific and honest about what you personally owned versus what the wider team, agency or manager was responsible for. Interviewers will probe this, and it's covered more directly in our interview questions guide.

Treating the portfolio as a static PDF. A short walkthrough you can talk through live, or a simple page you control and can update, tends to work better in an interview setting than a document emailed in advance and never referenced again.

How to present it

A simple, well-organised page or document beats an elaborate one. Structure it around the case-study format above, lead with your strongest and most relevant project for the specific role you're applying for, and be ready to talk through your reasoning on any project in more depth than what's written down. If you're presenting live in an interview, treat the portfolio as a prompt for discussion, not a script to read from.
