If you’re still on the fence about LinkedIn, it’s time to jump off. A 2013 social recruiting surveyby Jobvite concluded that LinkedIn is recruiters' top social network of choice for hiring. Recruiters use it to search for and contact candidates, keep tabs on potential candidates and vet applicants prior to an interview.
Your LinkedIn profile is just as important as your résumé. However, they are not the same thing and should be treated differently. There will be some crossover between the two, but your LinkedIn profile gives you the opportunity to create a more substantial version of your résumé. You can include elements in your profile that you cannot fit or easily include in a standard Word or PDF résumé.
