No, Google Docs resume templates are not good. Their selection is small, they waste space, and they don’t look good when downloaded to your computer as a Microsoft Word (DOCX) or PDF file.
Also, since Google Docs are stored on Google Drive, you have to adjust your Google Drive’s sharing settings for hiring managers to access your resume. Many hiring managers don’t regularly use Google Drive, so submitting anything other than your resume attached to your email as a DOCX or PDF file is an extra step for them to deal with.
