Behind the median

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

  • 10%Exceptional27 people
  • 37%Strong103 people
  • 40%Solid111 people
  • 13%Emerging36 people
  • 1%Unproven3 people

280 of the 500 people here carry an Eng Scorer tier.

130 of the 280 people here with a read sit in exceptional or strong, the top two of the five tiers, 46%. A tier is the band a 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.

44%Titles that rose145 of 332 classified people

  • 52%Stayed level171 people
  • 5%Fell16 people

332 of the 500 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 with one title here who then left, it's 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. Titles that match no rung are left out rather than guessed, and product, program and project managers are left out entirely as a different ladder. What's left leans towards people who have left: someone still here on one recorded title has nothing to measure against.

Public work

274 of the 500 people here whose profile was checked for public accounts. An account the check missed reads the same as no account, so this is a floor.

31% is the median across the 857 companies that can show this figure.

Where they live now, from the profile as it reads today, not where they sat while working at Airbnb: a metro here isn't an office there. The lower strip is the same metros across the whole map.
