Yes, you should make your resume read only. Making your resume read only in MS Word or Google Docs ensures that:
- Your resume formatting doesn’t change
- Spell-check doesn’t leave ugly red lines on your resume
- Hiring managers can’t accidentally edit your resume
Alternatively, you can save your resume as a PDF file. Resume PDFs can’t be edited and they’re easy for anyone to open and read.
If the job ad specifies which file format to submit your resume in, make sure you stick to that format.
