I don't think I've seen anyone provide a workable system where senior is reserved for people around 20 years of experience. What's that structure look like? Everyone from 1-20 years experience has the same title? There's definitely inflection points at years of experience: 0: Good enough to be hired 1-3: Solid team contributor 3-5: Best IC on a team 5-8: Lead a project/team 8+: Lead multiple projects Then from there it's increasing complexity of teachnical problems and project size. If you're insisting that senior applies only to the last level what do you call all those steps between 0 and 8.
