Resume Basics FAQ

What is a resume and why do I need one?

A resume is a formal document that summarizes your professional background, including your work experience, education, skills, and achievements. It serves as your personal marketing tool, designed to convince employers that you’re the right candidate for their position. You need a resume because it’s the standard requirement for job applications across virtually all industries. It provides employers with a quick overview of your qualifications and helps them decide whether to invite you for an interview. A well-crafted resume can open doors to opportunities, while a poorly written one can close them before you even get a chance to speak with a hiring manager.

How long should my resume be?

The ideal resume length depends on your career stage and experience level. For most professionals with less than 10 years of experience, a one-page resume is recommended. This forces you to be concise and include only the most relevant information. If you have 10-15 years of experience or more, a two-page resume is acceptable and often necessary to adequately showcase your career progression and achievements. However, never extend your resume to two pages just to fill space—every word should add value. Senior executives or academics may have three-page resumes or CVs, but for most job seekers, brevity and relevance are more important than length.

What sections should I include in my resume?

Every professional resume should include these core sections: contact information (name, phone, email, LinkedIn profile), professional summary or objective, work experience, education, and skills. Optional sections that can strengthen your resume include certifications, volunteer work, professional affiliations, publications, languages, awards and honors, and relevant projects. The key is to include sections that are relevant to the position you’re applying for. For example, if you’re applying for an international role, a languages section becomes essential. If you’re in a technical field, a certifications section might be more important than volunteer work.

Should I include a photo on my resume?

In most English-speaking countries, including the United States, Canada, UK, and Australia, it’s generally recommended NOT to include a photo on your resume. This is primarily to prevent unconscious bias and discrimination based on appearance, age, race, or gender. However, practices vary by country and industry. In some European countries, Latin America, and Asia, including a professional headshot is common and sometimes expected. If you’re applying internationally, research the norms for that specific country. When in doubt, leave the photo off unless explicitly requested. Your qualifications and experience should speak for themselves.

What’s the difference between a resume objective and a professional summary?

A resume objective is a brief statement about your career goals and what you’re seeking in a position. It focuses on what you want from the employer. For example: “Seeking a marketing coordinator position to develop my digital marketing skills.” A professional summary, on the other hand, focuses on what you offer the employer—your key qualifications, experiences, and achievements. For example: “Results-driven marketing professional with 5 years of experience increasing brand engagement by an average of 40% through targeted digital campaigns.” Professional summaries are generally more effective because they immediately demonstrate value to the employer. Objectives are better suited for career changers, recent graduates, or those with limited experience.

How far back should my work history go?

Generally, you should include 10-15 years of relevant work experience on your resume. This timeframe gives employers a comprehensive view of your recent career progression while keeping your resume focused and relevant. Older positions can be summarized in an “Earlier Career” or “Additional Experience” section with just job titles and company names, without detailed bullet points. If you have experience from 20+ years ago that’s particularly relevant to the position you’re applying for, you can include it, but be strategic. The goal is to demonstrate progression and relevant expertise without dating yourself or overwhelming the reader with outdated information.

Should I include references on my resume?

No, you should not include references directly on your resume. The phrase “References available upon request” is also outdated and wastes valuable space. Employers assume you have references and will ask for them at the appropriate time, typically during later stages of the interview process. Instead, prepare a separate reference sheet with 3-5 professional references, including their names, titles, companies, phone numbers, emails, and your relationship to them. Have this document ready to provide when requested. This approach keeps your resume focused on your qualifications while ensuring you’re prepared when references are needed.

What are the most common resume mistakes to avoid?

The most damaging resume mistakes include typos and grammatical errors, which suggest carelessness and lack of attention to detail. Other common errors include using an unprofessional email address, including irrelevant personal information (age, marital status, social security number), creating overly long resumes filled with responsibilities instead of achievements, using passive language instead of action verbs, having inconsistent formatting, including salary information, and failing to tailor the resume to the specific job. Additionally, using templates with overly creative designs that confuse Applicant Tracking Systems, listing references directly on the resume, and including outdated information or skills can all hurt your chances. Always proofread multiple times and consider having someone else review your resume before submitting.

How should I format my resume for Applicant Tracking Systems (ATS)?

Applicant Tracking Systems scan and parse resumes before human eyes see them, so ATS-friendly formatting is crucial. Use a clean, simple layout with standard section headings like “Work Experience” and “Education.” Stick to common fonts like Arial, Calibri, or Times New Roman in 10-12 point size. Avoid tables, text boxes, headers, footers, graphics, and images, as these can confuse ATS software. Use standard bullet points rather than special characters or symbols. Save your resume as a .docx file unless a PDF is specifically requested, as some ATS have trouble reading PDFs. Include relevant keywords from the job description naturally throughout your resume, particularly in your skills and experience sections. Spell out acronyms at least once, followed by the acronym in parentheses.

How often should I update my resume?

You should update your resume regularly, ideally every 3-6 months, even when you’re not actively job searching. This ensures you don’t forget important accomplishments, projects, or skills you’ve developed. Keep a “career accomplishments” document where you track achievements, metrics, and major projects throughout the year, making it easier to update your resume when needed. Definitely update your resume before starting any job search, after completing major projects or achieving significant results, when you acquire new skills or certifications, after receiving promotions or taking on new responsibilities, and before annual performance reviews (having an updated resume helps you articulate your value). Regular updates ensure your resume is always ready for unexpected opportunities.

Should I customize my resume for each job application?

Yes, absolutely! Customizing your resume for each application significantly increases your chances of getting an interview. This doesn’t mean rewriting your entire resume—rather, it means tailoring key sections to align with the specific job requirements. Start by carefully reading the job description and identifying the most important qualifications and keywords. Then adjust your professional summary to emphasize relevant experience, reorder or modify your bullet points to highlight the most pertinent achievements, incorporate keywords from the job posting (naturally, not forced), and emphasize skills that match the position requirements. You might also adjust which positions or projects you give more detail to based on their relevance. This targeted approach shows employers that you’ve taken the time to understand their needs and demonstrates how you specifically fit the role.
