4 most common titles, by people who held them.

Whether a title rose here

The level of the first title recorded here, against the last.

52%Titles that rose11 of 21 classified people

  • 52%Rose11 people
  • 48%Stayed level10 people

21 of the 22 people here had a title that could be placed on the ladder before and after.

A title rose when the last title recorded here sits higher on the ladder than the first; for someone who recorded one title here and then left, it is measured against the first title of their next role. The ladder runs intern, junior, mid, senior, staff or manager, principal, director, VP, then founder or C-level. A title that matches no rung is left out rather than guessed, and product, program and project managers are left out entirely, being a different ladder. That leaves 21 of the 22 people here classified, and it leans towards people who have left: someone still here on a single recorded title has nothing to be measured against.
