Steps to Follow:
Hover over Groups at the top of your home page, and select Group Directories from the drop-down menu.
Search for the groups that interest you using the Group Search box on the left.
In the same menu, you can also click on Groups that you might like and look at the groups that LinkedIn offers you, depending on your experience, studies, contacts, etc.
Once we have found a group that we want to join, we must click on the group’s name and click on the join group button.

The group administrators must accept and approve your request, and you will receive an email when you have joined the group (this is usually a fast process).
