Behind the median

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

  • 9%Strong3 people
  • 59%Solid20 people
  • 32%Emerging or unproven11 people

34 of the 34 people here carry an Eng Scorer tier.

Exceptional and strong are the top two of the five tiers. 3 of the 34 people here with a read sit in them, 9%. 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. A tier 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.

Where they studied

  1. UC Berkeley17.7%
  2. Columbia11.8%
  3. Cornell8.8%

The 3 most listed schools among the 34 people here with a school on file.

Of the 34 people here with a school on file, 6 list UC Berkeley, 4 list Columbia and 3 list Cornell. A person can list more than one school, so these overlap rather than add up.

Public work

38%have a public GitHub account on their profile

13 of the 34 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

56% of the people who have worked at Rewriting the Code 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 Rewriting the Code: 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.
