What is a Resume?

A resume is a 1-2 page document that summarizes your work experience, education, skills, and achievements. Its purpose is simple: get you an interview.

Think of it as a marketing document where you're the product. You have 6-8 seconds to convince a recruiter you're worth interviewing.

Resume vs. CV: What's the Difference?

  • Resume: 1-2 pages, used for jobs in US/Canada, focuses on relevant experience
  • CV: 3+ pages, used for academic/research positions or jobs outside US, comprehensive career history

Section 3: Work Experience (Most Important)

This is the heart of your resume. List your jobs in reverse chronological order (most recent first).

Format for Each Job:

Job Title

Company Name | City, State | Month Year – Month Year

Common Resume Mistakes

❌ Mistake #1: Listing Job Duties Instead of Achievements

Bad: "Responsible for managing social media accounts"
Good: "Grew Instagram following from 2K to 15K in 6 months, generating 500+ monthly website visits"

❌ Mistake #2: Using "I" Statements

Bad: "I increased sales by 20%"
Good: "Increased sales by 20%"

❌ Mistake #3: No Metrics or Numbers

Bad: "Managed a large team"
Good: "Managed team of 8 developers across 3 products"

❌ Mistake #4: Typos and Grammar Errors

Even one typo can get your resume rejected. Proofread 3 times. Use spell check. Have someone else review.

❌ Mistake #5: Generic Resume for Every Job

Recruiters can tell. Customize your resume for each application—especially the summary and skills sections.
