Core Concept

The cost of a bad hire is very high — not just in severance and backfill, but in morale. Whenever someone leaves a team, morale takes a hit regardless of whether the departee was a good teammate. You need a system for hiring that weeds out bad hires before they make it onto your team.

Clint Schmidt’s Three Criteria

Anyone must pass all three to be worthy of joining the team:

  1. Must possess intellectual horsepower — can they think through hard problems?
  2. Must not be a jerk — culture fit, emotional intelligence, collaboration
  3. Must be able to get emotionally invested in their work — do they care about the outcome, not just the paycheck?

The third one is underrated. Engineers who can’t get emotionally invested produce technically correct but soulless work. They don’t go the extra mile. They don’t catch the edge case that matters. They don’t fight for the user.

Jeff Bezos’s Three Questions

For every new hire:

  1. Will you admire this person? — do they raise the bar in a way that inspires?
  2. Will this person raise the average level of effectiveness of the group? — the “raising the bar” test
  3. Along what dimension might this person be a superstar? — what’s their spike?

The Coordination Overhead Trap

“The more you try to hire to solve the bottleneck the more coordination overhead slows things down even further.” — Andrew Bosworth (boz.com/articles/bandpass)

Hiring is not a linear scaling lever. Beyond a certain point, each new hire adds more coordination cost than productive capacity. This connects to Amdahls-Law — the sequential coordination overhead limits how much parallelization (headcount) can help. Before hiring, ask whether the bottleneck is actually parallelizable.

How These Connect

Both frameworks reject the “warm body” approach to hiring. Both insist on something beyond technical competence. Schmidt’s #3 (emotional investment) and Bezos’s #1 (admiration) point at the same thing: you want people who care, not just people who can.
