Tips for Writing a Better Costco Janitorial Staff Resume

1. Use a clear and concise format: Choose an easy-to-read font and use headings to organize your information into sections, such as Objective, Work Experience, Education, Skills, and Certifications. This makes it easier for hiring managers to skim through your resume and find the relevant details.

2. Customize your objective statement: Tailor your objective statement to the specific janitorial position at Costco you are applying for. Highlight how your skills and experience will benefit the company and contribute to its success.

3. Focus on relevant work experience: List your most recent job first and include any relevant janitorial or cleaning experience you have had in past jobs. Be sure to highlight tasks that demonstrate your ability to maintain cleanliness, follow safety procedures, and work efficiently.

4. Emphasize transferable skills: If you don't have direct janitorial experience, emphasize transferable skills that would be useful in a janitorial role, such as attention to detail, time management, problem-solving abilities, teamwork, communication skills, and customer service.

5. Include certifications or training: If you have any certifications or training related to janitorial work or safety procedures (such as OSHA guidelines), be sure to include this information on your resume.

6. Quantify achievements when possible: Use specific numbers or percentages when describing accomplishments in previous roles (e.g., "Reduced cleaning supply costs by 15% through more efficient inventory management").

7. Showcase awards or recognition: If you've received any awards or recognition for outstanding performance in a previous job – particularly one related to janitorial work – include this information on your resume.

8. Proofread carefully: Check for spelling errors, grammatical mistakes, formatting inconsistencies, and other issues that could make your resume appear unprofessional or difficult to read.

9. Keep it concise: Aim for one page if possible – hiring managers often spend just a few seconds scanning each resume, so it's crucial to keep your information concise and easy to skim.

10. Use action verbs: Start each bullet point with an action verb (such as "maintained," "implemented," or "managed") to make your resume more engaging and easier to read.
