How to improve your resume quickly in ANY (really!) amount of time. 
If you have <5 minutes: Run it through Grammarly. You'll quickly find out if you're making some easily avoidable grammar/spelling mistakes.
If you have <15 minutes: Use a resume scanner and make sure that your resume can beat ATS https://resumeworded.com/resume-scanner

4-6 hours: Send your resume to a friend and ask them to edit with the promise of buying them (virtual) coffee. This assumes that your friend will respond in 4-6 hours though. 
If you have ~48 hours: Submit your resume to ZipJob. They offer a free resume review from an actual person.
