Behind the median

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

  • 6%Exceptional6 people
  • 26%Strong25 people
  • 41%Solid39 people
  • 23%Emerging22 people
  • 4%Unproven4 people

96 of the 96 people here carry an Eng Scorer tier.

Exceptional and strong are the top two of the five tiers. 31 of the 96 people here with a read sit in them, 32%. 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.

43%Titles that rose34 of 80 classified people

  • 43%Rose34 people
  • 57%Stayed level or fell46 people

80 of the 96 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 80 of the 96 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 95 people here with a school on file.

Of the 95 people here with a school on file, 19 list UC Berkeley, 9 list MIT and 6 list Stanford. A person can list more than one school, so these overlap rather than add up.

Public work

54%have a public GitHub account on their profile

52 of the 96 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

75% of the people who have worked at Twitch and list a location live in the San Francisco Bay Area today, against 47% of everyone on the map.

Where they live now, from the profile as it reads today, not where they sat while they worked at Twitch: 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.
