This might seem obvious, but it is very important. Make sure your resume is updated with your most recent contact information. Recruiters and hiring managers often get thousands of resumes for one job position, so providing them with your email address, personal phone number, and home address will make contacting you for an interview much easier. When including your email address, be sure not to use addresses that are too casual.
In many cases, your resume is the first document a hiring manager will look at when reviewing your application, and therefore is a true “first impression.” Accordingly, it’s important to put time and effort into developing and maintaining an updated, accurate resume.
