Behind the median

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

  • 6%Exceptional4 people
  • 22%Strong15 people
  • 49%Solid33 people
  • 24%Emerging16 people

68 of the 68 people here carry an Eng Scorer tier.

Exceptional and strong are the top two of the five tiers. 19 of the 68 people here with a read sit in them, 28%. 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.

38%Titles that rose15 of 40 classified people

  • 38%Rose15 people
  • 63%Stayed level or fell25 people

40 of the 68 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 40 of the 68 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.

Public work

36 of the 68 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.

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