How to Write a Resume and Cover Letter That Win Interviews

Published:

In brief

A resume and cover letter win interviews when they are tailored to the specific job, built around measurable achievements, and formatted so both a hiring manager and an applicant tracking system (ATS) can read them. Guidance from Harvard Career Services, Purdue University's Online Writing Lab, and ATS research published by Jobscan point to a repeatable structure for both documents, summarized step by step below.

Job seekers searching for resume and cover letter advice are usually trying to solve two problems at once: getting past automated screening software and convincing a human reader to schedule an interview. Career-services offices and applicant-tracking-system (ATS) researchers describe overlapping but distinct rules for each goal.

Choosing a Resume Format

Purdue University's Online Writing Lab (OWL), a widely used academic writing resource, identifies several résumé format variations and recommends tailoring the document to the specific employer rather than sending one version to every opening.

Resume formats described by Purdue OWL
FormatWhat it does
ChronologicalLists work history in reverse order; the traditional, most common structure
Functional (skills-based)Organizes content around skill categories instead of a job-by-job timeline
Scannable / ATS-formattedBuilt specifically so applicant tracking software can read it before a person does

On length, Purdue OWL notes that while a one-page résumé remains the traditional expectation, employers are accepting longer résumés in certain instances, generally tied to how much relevant experience a candidate has.

Steps for Building the Resume

  1. Pick a format (chronological, functional, or a scannable/ATS version) based on your work history and the employer, per Purdue OWL.
  2. Include the core sections Purdue OWL lists: contact information, education, work experience, and skills or honors/activities.
  3. Put the exact job title from the posting in your resume headline; Jobscan cites research finding that resumes containing the exact job title received interview invitations at a rate reported as 10.6 times higher.
  4. Write bullet points that pair a specific skill with a measurable result instead of listing duties, as Jobscan recommends.
  5. Match the hard skills and language used in the job description, including both the long-form term and its acronym (for example, 'Search Engine Optimization (SEO)'), per Jobscan.
  6. Format for machine readability: use a single-column layout, avoid tables, text boxes and graphics, use standard section headings such as 'Work Experience' and 'Education,' and save the file as .docx or a text-based PDF, per Jobscan's ATS guidance.

Writing the Cover Letter

Harvard Career Services (FAS) describes the cover letter as a narrative companion to the resume rather than a repeat of it, built around three sections.

  1. Opening paragraph: name the position and organization and state a specific, genuine reason for applying rather than a generic statement of interest, per Harvard Career Services.
  2. Middle paragraph(s): describe concrete, quantified accomplishments; Harvard's own example is 'Grew a student org's Instagram following from 200 to 1,400' rather than simply stating a task was completed.
  3. Closing paragraph: restate interest directly and thank the reader, avoiding weak phrasing such as 'I hope to hear from you,' per Harvard Career Services.
  4. Keep the whole letter to one page, three to four short paragraphs, roughly 250 to 400 words, per Harvard Career Services.
  5. Use a standard font (Arial, Calibri, or Georgia) at 11 or 12 point, one-inch margins, single spacing within paragraphs, and save as a PDF unless the employer requests another format, per Harvard Career Services.

Your cover letter doesn't need to be perfect. It needs to be specific, honest, and written like a real person sent it.

Purdue OWL describes one page as the traditional expectation, but notes employers are accepting longer résumés in certain instances, generally depending on the candidate's amount of relevant experience.
How long should a cover letter be?
Harvard Career Services recommends one page: three to four short paragraphs, roughly 250 to 400 words.
Which resume format should I use?
Purdue OWL describes chronological (reverse-order work history), functional/skills-based, and scannable/ATS-formatted résumés as the main variations, chosen based on the candidate's background and the employer.
How do I get my resume past an ATS?
Jobscan recommends a single-column layout, avoiding tables, text boxes and graphics, using standard section headings, saving the file as .docx or a text-based PDF, and matching the exact job title and hard skills from the posting.
Should I include numbers in my cover letter, not just my resume?
Yes — Harvard Career Services' own example favors a quantified accomplishment ('Grew a student org's Instagram following from 200 to 1,400') over a vague description of a completed task.
