5 years work gap, is it criminal?

Is 5 years work gap criminal to big prestigious firms or colleges? Like, would it be discarded among other competitive individuals?

Is do have an explanation- i 31F was working for family busienss and I'd like to keep my professional life separate. I won't mention the company names, so I will leave it off my linkedin profile and resume.

But if i can get the next job that's relevant and well known, and work for another 5 years is this feasible to go back to good colleges and apply for consulting?

PS- i would love helpful answers 🙏 And I did go to a competitive college too, life just happened to me
