Keep your LinkedIn account professional. "Don't post what you had for lunch on LinkedIn!" Gindlesperger laughed. LinkedIn is a professional networking platform, and it should stay that way. "LinkedIn should showcase your skills, expertise, education, and experience," Gindlesperger said. In her administrative role, Gindlesperger knows just how much employers use LinkedIn to scope out a job candidate. "The first thing I do when reviewing job applicants: I pull up their LinkedIn profile and review it." Consider your LinkedIn account an extension of your resume, and count on employers reviewing it during the application process.
