What Are the 3 C's of a Resume?

The 3 C's of a resume are Clarity, Conciseness, and Consistency. These three principles form the foundation of any effective CV or resume, whether you're applying in London, New York, or anywhere in between.

Recruiters spend an average of 6–7 seconds on an initial resume scan. If your document fails on any of the 3 C's, it is likely to be discarded before anyone reads your experience in depth.

1. Clarity

Clarity means a recruiter or hiring manager can instantly understand who you are, what you do, and what value you bring — without having to decode jargon or hunt for key information.

How to achieve clarity:

Lead with a strong professional summary — 2–3 sentences that state your role, years of experience, and top achievement.

Use standard section headings — "Work Experience", "Education", "Skills". Avoid creative labels like "My Journey" that confuse applicant tracking systems (ATS).

Write in plain English — avoid buzzwords like "synergised cross-functional deliverables". Say what you actually did.

Use bullet points rather than dense paragraphs.

Example of unclear writing:

Leveraged holistic stakeholder engagement strategies to drive transformational organisational outcomes.

Rewritten with clarity:

Led cross-team projects with 4 departments, cutting project delivery time by 20%.

2. Conciseness

Conciseness means every word earns its place. A concise resume respects the reader's time and signals that you communicate efficiently — a quality every employer values.

Rules for conciseness:

One page for under 10 years of experience, two pages maximum for senior roles (see our guide on how many pages a resume should be).

Start bullets with strong action verbs: Delivered, Built, Reduced, Managed, Launched.

Cut filler phrases: "Responsible for" → just say what you did. "References available on request" → delete it entirely.

Limit bullet points to 3–5 per role — enough to show impact without padding.

The test: if a bullet point doesn't include an accomplishment or relevant skill, cut it.

3. Consistency

Consistency covers formatting, tense, punctuation, and tone throughout your entire document.

Consistency checklist:

Tense: Use past tense for previous roles (Managed, Delivered) and present tense for your current role (Manage, Lead).

Date format: Pick one style — "Jan 2022 – Mar 2024" or "01/2022 – 03/2024" — and use it everywhere.

Font and size: One font family, typically 10–12pt body text with consistent heading sizes.

Bullet punctuation: Either end all bullets with a full stop or none of them do. Don't mix.

Capitalisation: Consistent job title capitalisation (Senior Software Engineer vs senior software engineer).

Inconsistency — even small things like mismatched date formats — signals a lack of attention to detail. For a competitive London job market, that can cost you an interview.

Why the 3 C's Matter for ATS Systems

Beyond the human eye, your resume often has to pass through an Applicant Tracking System (ATS) before a recruiter ever sees it. ATS parsers reward Clarity (standard headings), Conciseness (keyword density), and Consistency (structured formatting).

You can check whether your resume passes ATS requirements with our free ATS Resume Checker — it scans your CV for keyword matches, formatting issues, and missing sections.
