How to Write This Resume

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

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]).

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 individual looking for a Big Data position where I can learn new things and advance my career.

  • 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%"). Do not include outdated technologies unless specifically required.

Real Examples

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

Don't

Including progress bars or subjective skill levels like 'SQL: Proficient'

Do

Listing specific languages such as Python, R, SQL

Don't

Mentioning outdated tools like SQL Server 2008

Do

Highlighting current and relevant technologies like AWS Redshift or Google BigQuery

Quick Tips

  • Prioritize your skills list by relevance to the job description. Highlight those that are most in-demand for big data roles.
  • Avoid listing soft skills separately; instead, demonstrate them through action-oriented bullet points under experience sections.
  • Ensure all listed technical skills are current and supported by practical projects or certifications.
  • When mentioning programming languages, specify any relevant frameworks or libraries you have proficiency with.

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

Analyzed complex data sets, delivering actionable insights that improved decision-making processes.

Quick Tips

  • Use strong action verbs at the beginning of each bullet point (e.g., Analyzed, Implemented, Led).
  • Quantify your achievements with specific metrics to demonstrate impact.
  • Highlight leadership roles and initiatives that showcase responsibility growth over time.
  • Focus on significant contributions rather than routine tasks.

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

Master of Science in Computer Science | University of California, Berkeley September 2014 – May 2016 - Coursework: Introduction to Programming, Data Structures, Database Systems, Object-Oriented Programming - Honors: Dean's List (Spring 2015) - GPA: 3.8

Quick Tips

  • List your degrees in reverse chronological order.
  • Focus on the most recent or relevant education details, especially if you have extensive work experience.
  • Include only significant achievements such as honors, scholarships, and notable projects.
  • Use bullet points to break down information for easier scanning.

06

Projects

Projects

Project Name | Tools/Technologies Used - Briefly describe what you created and its purpose - Highlight specific challenges you solved - Link to portfolio or 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 your portfolio or demo if possible. Focus on projects that show problem-solving skills and relevant tools 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 created and why it matters.
