Whether a title rose here

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

57%Titles that rose16 of 28 classified people

  • 57%Rose16 people
  • 43%Stayed level or fell12 people

28 of the 34 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 with one title here who then left, it's 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. Titles that match no rung are left out rather than guessed, and product, program and project managers are left out entirely as a different ladder. What's left leans towards people who have left: someone still here on one recorded title has nothing to measure against. A direction holding fewer than 3 people is printed with the one next to it, because that few is a person rather than a pattern.

16 of the 34 people here whose profile was checked for public accounts. An account the check missed reads the same as no account, so this is a floor.
