As someone who has just joined the workforce in the past few years, I have never understood LinkedIn. The job hunting seems like a budget version of Indeed or similar. The "social media" aspect is by far the least engaging, most spammy, useless stream of information that's possible. The recruiters on there ruin things even further, adding to the pile of spam that we already deal with. I really don't see the point of LinkedIn past declaring who you work for.
