Behind the median

Everyone here with an Eng Scorer read, placed in their caliber tier.

113 of the 114 people here carry an Eng Scorer tier.

Exceptional and strong are the top two of the five tiers. 17 of the 113 people here with a read sit in them, 15%. A tier is the band an Eng Scorer caliber score falls in, so this is the same measurement as the median on the caliber card, opened up.

Whether a title rose here

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

39%Titles that rose30 of 77 classified people

  • 39%Rose30 people
  • 61%Stayed level or fell47 people

77 of the 114 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 77 of the 114 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. A direction holding fewer than 3 people is printed together with the one next to it, because a bucket that small is a person rather than a pattern.

The 8 most listed schools among the 113 people here with a school on file.

Of the 113 people here with a school on file, 20 list UC Berkeley, 8 list Georgia Tech and 8 list UC San Diego. A person can list more than one school, so these overlap rather than add up.

Public work

one square is one in a hundred
32%have a public GitHub account on their profile

36 of the 113 people here whose profile was checked for public accounts. An account the check did not find reads the same as no account, so this is a floor rather than a census.

Across the 325 companies on the map that can show this figure, the median is 38%.

Where they are now

89% of the people who have worked at Lawrence Livermore National Laboratory and list a location live in the San Francisco Bay Area today, against 47% of everyone on the map.

113 of the 114 people who worked at Lawrence Livermore National Laboratory list a location, and every share here is over those 113.

Where they live now, from the profile as it reads today, not where they sat while they worked at Lawrence Livermore National Laboratory: a metro here does not mean the company has an office in it. The lower strip is the same metros across the whole map, for comparison.
