When you apply for a job on or via LinkedIn you can see how many that applied or clicked the link before you. You can then make a judgement call, is it worth applying when 50 already did? But LinkedIn trick us. The click/apply counter doesn't match the clicks. They want to keep the clicks down so people get trick to think they have a better chans to get the job then they really have. In thet way more people apply and LinkedIn ears more revenue.
