Cavalli agrees. “It’s not enough to only post a profile and check your news feed. There are a lot of lurkers–people who have an online profile but don’t do anything or engage in any meaningful way. You need to give to the social networking communities, participate in group discussions, share expertise, point someone to an article. You have to work it. While it can feel uncomfortable putting yourself out there, if you’re looking for a job, it’s not the time to be timid.”
