Behind the median

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

  • 13%Strong5 people
  • 39%Solid15 people
  • 34%Emerging13 people
  • 13%Unproven5 people

38 of the 38 people here carry an Eng Scorer tier.

Exceptional and strong are the top two of the five tiers. 5 of the 38 people here with a read sit in them, 13%. 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.

Where they studied

  1. UCLA11.1%
  2. USC8.3%

The 2 most listed schools among the 36 people here with a school on file.

Of the 36 people here with a school on file, 4 list UCLA and 3 list USC. A person can list more than one school, so these overlap rather than add up.

Public work

one square is one in a hundred
45%have a public GitHub account on their profile

17 of the 38 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

42% of the people who have worked at ODF and list a location live in Los Angeles today, against 6% of everyone on the map.

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