Behind the median

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

  • 4%Exceptional3 people
  • 36%Strong24 people
  • 48%Solid32 people
  • 12%Emerging8 people

67 of the 71 people here carry an Eng Scorer tier.

Exceptional and strong are the top two of the five tiers. 27 of the 67 people here with a read sit in them, 40%. 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.

52%Titles that rose32 of 61 classified people

  • 52%Rose32 people
  • 43%Stayed level26 people
  • 5%Fell3 people

61 of the 71 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 61 of the 71 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.

The 6 most listed schools among the 66 people here with a school on file.

Of the 66 people here with a school on file, 7 list UC Berkeley, 6 list UCLA and 5 list University of Waterloo. A person can list more than one school, so these overlap rather than add up.

Public work

one square is one in a hundred
51%have a public GitHub account on their profile

34 of the 67 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

48% of the people who have worked at Brex and list a location live in New York today, against 33% of everyone on the map.

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