Someone said :
Do people use linkedin? how do you use it? I applied for a job recently and someone who works in more or less the same job added me - I'm not sure if it's a coincidence - I don't use linkedin that much. Should I contact her? I am half expecting to be called for interview for the job.
LinkedIN is for business networking. It's very useful for making business contacts, joining commercial groups, job hunting. If you are middle management and up you really should have a LinkedIN profile as employers will look you up.
Your profile on LinkedIN is basically an up to date resume..
