"Don't ever expect a recruiter to represent you if you cannot positively and professionally represent yourself on LinkedIn," Leclaire, who is also founder and chief evangelist of Ready Set Rock Academy, told Business Insider.
"If your LinkedIn profile is bare and your picture looks like it's cropped from a group photo from a family wedding, a recruiter will pass you up," she added.
Dickstein said you don't need to hire a professional photographer, necessarily, but make sure your head is visible, the background is simple, your face is shown clearly, and you're in casual business attire.
And yes, anyone can tell if you've cropped out your friends or a wine glass, Dickstein said.
