This is the final module. Before you click submit on any application, run through this checklist. It takes 5–10 minutes and catches the kind of mistakes that are invisible when you’ve been staring at your resume for hours.

This module also includes the two quick-reference tables — common resume mistakes and word replacement — that belong on your desk for every revision.


Page Count Rules

One Page

Use a one-page resume when:

  • You’re a new grad or have under 5 years of experience
  • The company or role explicitly asks for it
  • The industry culture favors brevity (some startups, design roles, certain sales environments)

Two Pages

Two pages is the standard for 5–15 years of experience. Use it when:

  • Your professional history genuinely requires the space
  • You have significant projects or publications worth listing
  • You’re in a senior IC, staff, or management role with a longer track record

Three Pages or More

Almost never appropriate unless:

  • You’re an academic submitting a CV (different document type, different conventions)
  • You’re a C-suite executive with 20+ years and a board member / advisory history
  • Your field requires a full publication or patent list

The universal rule: every line should earn its place. If you’re struggling to fill page two, stop at page one. If you can’t get under three pages, cut the oldest and least relevant roles first.


File Format and Submission

When to Submit PDF

Almost always. PDF preserves your formatting exactly as you designed it. The human recruiter sees what you intended them to see.

When to Submit .docx

When the job posting or ATS explicitly asks for Word format. Some older ATS systems parse .docx better than PDF. If both are accepted and you’re unsure, submit the PDF.

Naming Your File

FirstLast_Resume.pdf or FirstLast_Resume_CompanyName.pdf

Never:

  • resume_final_v3_FINAL_USE_THIS.pdf
  • My Resume.pdf
  • resume(2).docx
  • untitled.pdf

A recruiter’s downloads folder has dozens of resumes named “resume.pdf.” Yours should be findable the moment they go looking.

Email Submissions

  • Subject line: Application for [Job Title] — [Your Name]
  • Keep the body to 3–4 sentences. The resume is attached — don’t re-summarize it.
  • If you were referred, mention the referrer’s name in the first sentence.

The Pre-Send Checklist

Run through this before every submission:

  • Contact info is current — email, phone, LinkedIn, city/state (not full address)
  • No typos — run spellcheck, then read it out loud
  • Dates are consistent and accurate — same format throughout, no gaps you haven’t addressed
  • Every bullet starts with a strong action verb
  • ATS keyword match is at least 60–70% — use the ATS Resume Improver against the job description
  • No tables, text boxes, or multi-column layouts
  • No graphics, photos, or skill rating bars
  • File is named correctly — FirstLast_Resume.pdf
  • PDF opens correctly on a different device or in a browser
  • LinkedIn profile matches your resume’s dates and titles
  • A second person has read it — fresh eyes catch errors you’ve become blind to
  • You can speak to every item on this resume confidently in an interview
  • Summary is tailored to this specific role — not generic across all applications
  • Most relevant experience appears first within each role

Run this checklist, not as a formality, but because most errors that reach recruiters are things the checklist would have caught.
