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.
Some companies will indicate that they want you to submit a CV rather than a resume. A CV and a resume are not the same. CV stands for “curriculum vitae” and is meant to be an expansion of your resume. It is much longer than a resume, often three pages or more, and focuses mainly on your academic and professional accomplishments, with a particular focus on education.
