If you don't have any work experience, then a company wants to know what extra
activities you did in school to see if you are active. It is best to list a
couple of things describing what the group is and what role you had in the
group. If you were not a part of any group, it might be ok to make something
up. It is hard to verify this so they will not find out. But it could back
fire, if the interviewer happened to be in the same group at the same
university.
If you don't have work experience, then you will need to say something to show
them that you learned some valuable lessons such as team work. I suggest you to
reflect on what you did during school and create a list of what you learned.
