One of the most frustrating things for me when I was a recruiter was looking at a candidate's resume, deciding that I wanted to call them, and then having to search the resume to find the candidate's contact information.
Part of your job as a jobseeker is to make a recruiter's life easy. And the best way to make a recruiter's life easy is to make it easy to get in touch with you.
Your contact information on your resume belongs at the top of the resume.
It doesn't matter to me whether it's in the top left, center, or right, it just needs to be at the top.
It doesn't need to be on the side of your resume.
It definitely doesn't need to be on the bottom of your resume (it stuns me how often this happens).
Your contact information needs to be on the top of your resume.
You should have your name, the best phone number to reach you on, a professional email address, and your LinkedIn profile URL. You can also include links to portfolios in your contact information as well.
You have 6 seconds to capture a hiring manager's attention. Don't waste precious time by making them hunt for how to get in touch with you!
