If you have major gaps in employment, there are a few ways to make them less noticeable like a change of resume foramt. It is important to be honest about gaps in your resume and not try to cover them up, but to also make them seem productive and intentional. Adding volunteer work or classes in the time you were unemployed is highly valuable and fairly simple to get starter with.
Also be sure to include your city, state or zip code in your contact info, since employers will sometimes search Applicant Tracking Systems with these criteria. It’s also important for ATS to have this information at the top of your page, otherwise it may not be parsed into your candidate profile, making it harder for HR to find or remember your resume.
