I live, work, recruit and train job seekers as a LinkedIn profile writer in UK. This answer proceeds accordingly.
As a LinkedIn coach for job seekers for over a decade, I can tell you that I've seen amazing LinkedIn profiles from students and horrible LinkedIn profiles from established professionals.
There is something to unpack in your question.
- Simple LinkedIn profile. No. You do not want a simple profile. There is no such thing as a good profile that is also simple. Either it’s a good profile, or it’s simple. Things cannot coexist.
- Excellent skills/interests. If you have them, the relative lack of work is not a hindrance at all.
- Little work experience. That's not a problem: as I said above, I've seen killer profiles of college students.
