How to Write This Resume

How to Write This Resume

Expert guidelines and best practices for each section of your resume.

01

Contact

Contact

First Name Last Name City, State, Zip Code Phone Number | Email Address LinkedIn Profile URL | Portfolio URL (Optional)

General Guidelines

Your contact information is the first section recruiters see. Keep it concise and professional. Ensure your email address is appropriate (e.g., [email protected]). Include your LinkedIn profile for a comprehensive view of your professional journey. A portfolio or personal website is recommended for creative, technical, or design roles.

Avoid This

Do not include your full physical address (street number/name) for privacy reasons. Avoid including personal details like marital status, age, photo, or social security number unless specifically required in your country. Don't use unprofessional email addresses. Do NOT include GitHub links for artists - use ArtStation, Behance, or portfolio sites instead.

02

Summary

Summary

Professional Title Result-oriented [Role Name] with [Number] years of experience in [Key Skills/Industries]. Proven track record of [Major Achievement]. Skilled in [Key Technologies/Skills]. Committed to delivering [Specific Value] for [Target Industry/Company type].

General Guidelines

A professional summary is your elevator pitch. It should be 3-5 sentences long, summarizing your experience, key skills, and major achievements. Tailor it to the job description by using relevant keywords. Focus on what makes you unique and the value you bring to potential employers.

Avoid This

Avoid generic objectives like 'Looking for a challenging role to grow my skills.' Recruiters want to know what value you bring to them, not what you want from them. Don't use first-person pronouns (I, me, my). Keep it concise and impactful.

Real Examples

Compare a weak objective with a strong professional summary.

Don't

Objective: I am a hard-working candidate looking for a junior machine learning role where I can learn and grow.

Do

Junior Machine Learning Engineer with hands-on experience in NLP, data preprocessing, and model evaluation. Built sentiment analysis and recommendation projects with TensorFlow, PyTorch, Python, and SQL. Comfortable documenting experiments, comparing model metrics, and explaining results to product and data teams.

Don't

Objective: I seek an opportunity to grow my machine learning skills while contributing positively to the company's growth.

Do

Junior Machine Learning Engineer focused on NLP and production-ready data workflows. Refactored preprocessing scripts to reduce repeated training-prep time by 20% and built PyTorch recommendation prototypes for senior engineer review.

Quick Tips

  • Quantify achievements where possible (e.g., 'Increased revenue by 20%')
  • Keep it under 5 lines for readability
  • Use strong action verbs to start sentences
  • Tailor the summary to match the job description

03

Skills

Skills

Technical Skills - Languages: [List] - Frameworks: [List] - Tools: [List] Soft Skills - [Skill 1], [Skill 2], [Skill 3]

General Guidelines

Group your skills logically (e.g., Languages, Frameworks, Tools). Focus on hard skills relevant to the job. List skills in order of proficiency or relevance. Soft skills are better demonstrated through bullet points in your experience section rather than a bare list.

Avoid This

Do not list skills you are not comfortable using in an interview. Avoid using progress bars or percentages to rate your skills (e.g., "Java: 80%") as they are subjective and often misinterpreted. Don't include outdated technologies unless specifically required.

Real Examples

Practical example showing do's and don'ts for skills

Don't

Java, C++, Python (75%), TensorFlow (80%)

Do

Python, TensorFlow, PyTorch

Quick Tips

  • Prioritize your technical skills by relevance to the job description and industry standards.
  • Avoid listing overly generic or basic skills that are common among all candidates. Focus on unique competencies.
  • Use action verbs and short phrases for soft skills, such as 'collaborates effectively' instead of just 'team player'.
  • Keep your skill list concise; aim to highlight no more than 10-15 key technical skills.

04

Experience

Experience

Job Title | Company Name | Location Month Year – Month Year - Action Verb + Context + Result (Quantified) - Led [Project] resulting in [Outcome]... - Collaborated with [Team] to implement [Feature]...

General Guidelines

This is the core of your resume. Use reverse-chronological order (most recent first). Start each bullet with a strong action verb. Focus on achievements and impact, not just duties. Use numbers to quantify your impact (dollars, percentages, time saved, users affected). Show progression and increasing responsibility.

Avoid This

Avoid passive language like 'Responsible for...' or 'Tasked with...'. Don't list every single daily task; focus on significant contributions and measurable outcomes. Avoid jargon that recruiters outside your field won't understand.

Real Examples

Practical example showing do's and don'ts for experiences

Don't

Responsible for cleaning datasets and ensuring accuracy of machine learning models.

Do

Cleaned large datasets, improving model accuracy by 15%.

Don't

Worked on a project involving the development of an ML model.

Do

Developed a text classification model using TensorFlow, increasing customer support response accuracy by 30%.

Quick Tips

  • Use strong action verbs such as 'implemented', 'developed', and 'enhanced' to start each bullet point.
  • Quantify your achievements with numbers and metrics where possible to illustrate the impact of your work.
  • Highlight projects or initiatives that demonstrate leadership, innovation, or substantial contributions to business outcomes.
  • Ensure each experience shows a progression in skills and responsibilities over time.

05

Education

Education

Degree Name | University Name | Location Month Year – Month Year - Relevant Coursework: [Course 1], [Course 2] - Honors/Awards: [Award Name] - GPA: X.X (if above 3.5)

General Guidelines

List your highest degree first. If you have significant work experience, keep the education section brief. Include your GPA only if it is above 3.5 or if you are a recent graduate. Highlight relevant coursework, academic projects, honors, or leadership roles.

Avoid This

Do not include high school details if you have a college degree. Avoid listing every single course you took; select only the most relevant ones. Don't include graduation dates from decades ago if age discrimination is a concern in your field.

Real Examples

Practical example showing do's and don'ts for educations

Don't

Bachelor of Arts in English | University of California, Berkeley | Berkeley, CA September 2016 – May 2020 - Coursework: Literature Studies, Modern Languages, Composition and Rhetoric - GPA: 3.8

Quick Tips

  • Start with your most recent and relevant degree.
  • Highlight specific courses that are directly related to machine learning or data science.
  • Include honors or awards if they demonstrate your academic excellence in a meaningful way.
  • Keep the section concise, focusing on key details such as GPA (if above 3.5), relevant coursework, and significant achievements.

06

Projects

Projects

Project Name | Technologies Used - Briefly describe what you built and its purpose - Highlight a specific technical challenge you solved - Link to GitHub or live demo if available

General Guidelines

Projects are excellent for demonstrating practical skills, especially if you lack work experience or are changing careers. Include a link to the GitHub repo or live demo if possible. Focus on projects that show problem-solving skills and relevant technologies for the target role.

Avoid This

Don't include trivial tutorials unless you significantly expanded on them. Avoid projects that are outdated, incomplete, or irrelevant to the role you're applying for. Don't just list technologies—explain what you built and why it matters.

Real Examples

Practical example showing do's and don'ts for projects

  • Detail how you approached and solved a technical challenge within the project, highlighting unique problem-solving skills.
  • Provide context for why the project matters; explain its impact or potential application.
  • Link to GitHub repositories or live demos if available to allow recruiters to see your work in action.

Frequently Asked Questions

Common questions about this role and how to best present it on your resume.

Emphasize practical projects, Python, SQL, model evaluation, data preprocessing, and clear examples of how you tested or improved models. For early-career candidates, well-scoped projects and internships can carry as much weight as formal job titles.

Describe the dataset, model type, tools, and result without overstating ownership. Show how you cleaned data, measured performance, documented tradeoffs, or collaborated with product, engineering, or analytics teammates.

Yes. Include projects that solve a real problem, use relevant tools, and show measurable evaluation. Add GitHub links when the code is clean enough for a recruiter or technical reviewer to inspect.
