Besides having a great profile, there are multiple other ways to use LinkedIn to help in career management or job search. One of those options is to join a LinkedIn Group(s). From professional to hobby-related, there is a group for nearly everyone. You can contribute to ongoing discussions, start a discussion yourself, see what jobs a particular group has advertised, learn from industry experts, and find potential connections.
Just go to the Interests Tab at the top of the page and click Groups. LinkedIn will make suggestions based on your profile. My suggestion is to join local groups (this is where the jobs will be advertised), professional groups that have a LinkedIn Group as well, alumni groups, and company “alumni” groups. LinkedIn will allow you to join up to 50 groups, so you can have quite a selection. Always look at the group description first, how many members are in the group, and how active it is to make the right selections for you. To your job search and career success!
