3 most common titles, by people who held them.
Whether a title rose here
The level of the first title recorded here, against the last.
50%Titles that rose13 of 26 classified people
- 50%Rose13 people
- 50%Stayed level or fell13 people
26 of the 38 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.

The 3 most listed schools among the 38 people here with a school on file.
7 of the 38 people here with a school on file list Stanford, 7 list UC Berkeley and 3 list UCF. A person can list more than one, so these overlap.
Public work
one square is one in a hundred
76%have a public GitHub account on their profile
29 of the 38 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.
31% is the median across the 857 companies that can show this figure.
Where they are now
66% of the people who have worked at Docker and list a location live in the San Francisco Bay Area today, against 41% of everyone on the map.
