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.
Regardless of the type of resume you choose, aim to tailor your resume to the job you are applying to. While it’s perfectly acceptable to use a resume template, which you adapt to fit each job description, it’s a bad idea to send the same exact resume to multiple openings, even within the same field.
