Resume Writing

This deck walks you through the fundamentals of putting together a strong resume, starting with the basics of what a resume is and what it's meant to do. You'll explore the three main resume formats (chronological, functional, and hybrid) and learn when each one is the best fit for your situation. The cards then move through the key sections of a resume, including contact information, professional summary, work experience, education, and skills, with guidance on how to format and order each part.

It's a great starting point if you're writing your first resume, returning to the job market after a break, or simply wanting to refresh your knowledge before an application. Career changers and recent graduates may also find it especially useful, since the deck addresses common questions like when education should appear before experience and how to highlight transferable strengths.

To get the most out of these cards, try reviewing them in short sessions over several days rather than cramming them all at once. Spaced repetition helps you move from simply recognizing the answers to actually recalling them when you're sitting down to write or update your own resume. A helpful habit while studying is to pause after each card and think about how you'd apply that concept to a real document, since the goal is practical, not just theoretical.

A resume is a concise, tailored document that summarizes your professional experience, education, skills, and accomplishments to showcase your qualifications to potential employers. It typically spans one to two pages and serves as your first impression to recruiters and hiring managers. The primary purpose of a resume is not simply to list where you have worked, but to secure an interview by highlighting your most relevant qualifications and demonstrating your fit for a specific position.

Most resumes fall into one of three formats. The chronological resume organizes work history in reverse order, beginning with the most recent role, and is the most common and recruiter-preferred format when you have a steady work history with no significant gaps. The functional resume shifts the focus away from dates and instead emphasizes skills and capabilities, making it ideal for career changers, individuals re-entering the workforce, or anyone whose most marketable strengths are transferable rather than tied to a specific timeline. A hybrid resume combines the strengths of both approaches, leading with a skills summary and then presenting a reverse-chronological work history; this works well for candidates with both strong skills and solid experience.

In terms of length, one page is the ideal target for most professionals and is essential for early-career candidates. Two pages are appropriate for senior leaders, executives, or those with extensive relevant experience that cannot be trimmed without losing impact. Hitting the one-page mark usually requires prioritizing the most relevant information, using tight formatting with margins between half an inch and one inch, concise bullets, and a font size of 10 to 11 points so that every word earns its place on the page.

Every strong resume is built from a set of clearly labeled, scannable sections. At the very top, contact information must be prominent and include your full name, a professional email address, phone number, a LinkedIn profile or portfolio URL, and your city and state without a full street address. Directly beneath the contact block, a professional summary offers a three-to-five sentence overview that highlights your key strengths, relevant experience, and career goals. A summary is employer-focused, designed to grab attention immediately by showing your value; it differs from a career objective, which centers on what you want. Use summaries for most applicants, and reserve objectives for entry-level candidates whose goals still matter to employers.

The work experience section is the heart of most resumes and lists your professional roles in reverse chronological order, including job title, company, location, dates of employment, and four to six accomplishment-focused bullet points per role. A useful guideline is to focus on the last ten to fifteen years of relevant experience. Education typically follows experience, listing degrees, institutions, and graduation dates along with relevant honors or a GPA above 3.5; however, education should appear before experience if you have less than two to three years of professional work or if your degree is highly relevant to the target job, such as a recent graduate applying to a research position.

The skills section should list roughly eight to twelve relevant hard and soft skills, matched to the language of the job description. Skills may be presented as bullet points or as a simple skills matrix, a table grouping categories like Technical, Soft, and Tools for quick scanning, which is especially useful in technical resumes. Certifications belonging on the resume should be current and job-relevant, listed with the issuing body and year, such as a PMP credential from PMI earned in 2023. Throughout the document, dates should follow a consistent month and year format, such as Jan 2020 to Present, and a clean visual hierarchy can be created by using bold for job titles and company names and italics for dates.

The strongest resumes describe accomplishments rather than duties, and they do so with language that conveys impact. Action verbs such as led, developed, achieved, optimized, or streamlined should open each bullet point, instantly framing you as someone who takes initiative and delivers results. To make these claims credible, quantify achievements whenever possible by attaching numbers, percentages, or dollar amounts. Replacing "Improved sales" with "Increased sales by 30 percent over two quarters" provides concrete evidence of your contribution and helps your resume stand apart from generic lists of responsibilities.

A reliable way to build each bullet is the STAR method, which stands for Situation, Task, Action, and Result. You begin by describing the context, clarify your specific responsibility, name the action you took, and close with the outcome you achieved. Following this pattern keeps bullets specific and results-oriented rather than vague. Each bullet should fit on one to two lines, use parallel grammatical structure, maintain consistent tense (past tense for previous roles and present tense for your current position), and focus on what you accomplished rather than what was expected of you.

Special structural situations also benefit from clear handling. Promotions within a single company can be presented by listing each promoted role separately with its inclusive dates, or by noting the promotion within the top title. Holding multiple job titles at one company can be handled by listing the company once with overall dates and using sub-bullets for each title, or by stacking separate entries together with an emphasis on growth. Freelance or self-employment should be treated as a job, using your name or company as the employer, listing key clients or projects, and quantifying your results, with the option to group short gigs under a single entry.

Tailoring a resume means more than swapping a job title at the top. Read the job description carefully and identify the keywords, required skills, and core competencies it emphasizes, then mirror that language in your summary, skills, and experience sections. This makes your document more relevant to a human reviewer and dramatically improves compatibility with applicant tracking systems. ATS, or Applicant Tracking System, is software that scans and scores resumes before a person ever sees them, so optimizing for ATS means using standard section headers such as Work Experience or Education, spell out acronyms at first mention, avoid complex tables or graphics that confuse parsers, and incorporate exact phrases from the posting like Python programming or project management without stuffing keywords unnaturally.

The level of tailoring depends on the field. For tech roles, lead with technical skills, include a GitHub or portfolio link, and use industry terms such as Agile, Docker, or cloud-native while quantifying contributions through metrics like lines of code, uptime improvements, or deployments. For creative industries, you can introduce subtle design elements, restrained use of color, and a portfolio link, but the document must remain readable and still parseable by ATS software. For executives, summaries should focus on leadership, strategic impact, and revenue results, for example, highlighting twenty or more years of experience driving growth of half a billion dollars or more.

For career changers, the strategy is to lead with a transferable skills section, often using a functional or hybrid format, and to craft a targeted summary that connects past experience to the new field. An advanced ATS bypass approach is to include the target job title in your summary, use standard section headings, spell out acronyms on first use, and test your document using free ATS simulators available online. Saving the final file as a PDF using a name such as FirstName_LastName_Resume.pdf preserves formatting and ensures any embedded hyperlinks remain clickable for digital submission.

Several career scenarios require specific resume strategies. Entry-level candidates should emphasize education, internships, academic projects, extracurricular activities, and transferable soft skills, often using a functional or hybrid format that foregrounds capabilities over a short work history. Candidates with employment gaps can briefly explain shorter breaks through freelance work, volunteering, continued education, or a labeled Career Break entry, focusing on skills gained during the gap; for longer gaps, a functional format can de-emphasize chronology while keeping the focus on strengths.

Those with confidential roles, such as work for government agencies or proprietary corporate projects, should describe their experience with generic titles and company descriptions like Fortune 500 Tech Firm, only with prior approval, while highlighting transferable achievements. Academic professionals preparing for research or faculty positions typically use a CV rather than a resume; CVs are two or more pages and include publications, presentations, and grants, but they are not appropriate for most industry jobs. When importing a LinkedIn profile as a starting point, exporting it as a PDF provides a useful skeleton, but the result is often generic and should always be customized to the specific opportunity.

A few additional decisions round out special situations. Include hobbies or interests only when they are directly relevant to the job or demonstrate a key competency, such as marathon running for roles emphasizing endurance, and keep the section brief. Omit photos in the United States and most Western countries to avoid introducing bias, including them only when standard in your industry or region, such as acting portfolios. For freelance and self-employment, group shorter gigs together if needed, treat the work as a formal role, and quantify client outcomes so recruiters can quickly see your impact.

Final presentation is often what separates a competitive resume from one that gets passed over. Choose professional, readable fonts such as Arial, Calibri, or Times New Roman in a 10 to 12 point size, and avoid decorative faces or sizes below 10 points that hurt both readability and ATS parsing. References should not appear on the resume; either omit them entirely or include a brief note such as References available upon request, and prepare a separate reference sheet if and when it is requested.

Proofreading is non-negotiable. Read your resume aloud to catch awkward phrasing, run it through tools like Grammarly for spelling and grammar checks, and ask a trusted friend or mentor for a second opinion. Watch for typos, inconsistent date formatting, mismatched tenses, and any unusual characters that ATS software might misread. Common resume mistakes to avoid include generic content, listing job duties instead of achievements, poor formatting, embellishments or outright lies, and irrelevant personal details such as age or marital status that can introduce bias and distract from your qualifications.

Finally, remember that the resume works hand in hand with the cover letter. The resume provides the structured facts of your career, while the cover letter tells the story, explains your fit, and lets you elaborate on the highlights that the resume only briefly mentions. Together, a polished, tailored resume and a compelling cover letter create a coherent first impression that moves you from the applicant pool to the interview shortlist.
