Excellent post and it has been duly distributed to my team.
On your Post Discussion Items in Groups, you state:" 1.However, if you post a discussion item about your opportunities there’s a chance you will see some relevant responses.
2.Or, post an interesting industry-specific question in the hopes that you will hear from experts."
I agree and disagree here. 1.Many of these groups have recruiters posting positions left and right, where it really should be an area for SME's to answer questions or to disseminate their knowledge. Nothing irks me more than seeing groups spammed with recruiter posts- UNLESS the groups are specifically geared towards jobs and careers.
2.Yes, yes yes!- post a question and hopefully you'll her back from an a SME that you can network outside of the group
The Company Pages Feature is a little goldmine and offers insight on career paths,title levels, diversity stats and more.
Love the E-grabber tool for LI/Excel.
Lastly, many people will update their Status regularly in either "What are you working on?" (i.e. Currently looking for SAP Consultants in the Bay Area) or within their profile stating something along those lines. Result? Your network gets a Network Update from you and perhaps a person looking for an opportunity will reach out to YOU. Now that's passive candidate networking ;-)
