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

- 40%Rose12 people
- 60%Stayed level or fell18 people
30 of the 36 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.
