Behind the median

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

  • 4%Exceptional4 people
  • 32%Strong33 people
  • 44%Solid45 people
  • 20%Emerging or unproven20 people

102 of the 102 people here carry an Eng Scorer tier.

Exceptional and strong are the top two of the five tiers. 37 of the 102 people here with a read sit in them, 36%. 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.

Whether a title rose here

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

57%Titles that rose46 of 81 classified people

  • 57%Rose46 people
  • 40%Stayed level32 people
  • 4%Fell3 people

81 of the 102 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 81 of the 102 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.

Public work

51 of the 102 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

61% of the people who have worked at Affirm and list a location live in the San Francisco Bay Area today, against 47% of everyone on the map.

All 102 people who worked at Affirm list a location, and every share here is over them.

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