| A interview debrief feels “responsible” (It’s not)
Most founders treat the debrief as a best practice. This is understandable (and very normal).
It feels collaborative and thoughtful. In reality, however, the debrief only exists because the interview failed to produce clear signal.
If an interview did its job, there should be nothing to debate.
| What actually happens in debriefs
Let’s try a thought experiment: Think about the last debrief you sat in…
Opinions were shared instead of data-driven observations
Memory or hazy recollections replaced evidence
Confidence likely outweighed accuracy
The loudest voice likely set the tone
By the end of the debrief, it probably felt that the group was fully aligned. That feeling is deceptive.
Alignment is not clarity, and is often mistaken for conformity.
| Discussion does not enhance signal. It contaminates it
Every minute spent talking about a candidate after the interview introduces distortion. (and costs money!).
First of all, signal decays. What the candidate actually said matters less than how it is retold.
Second, social bias creeps in. Founders anchor on each other’s reactions instead of the work.
This is how hiring becomes political without anyone intending it to.
| Strong interviews make decisions obvious
High-signal interviews are designed to answer a single question.
Not “Do we like this person?”
Not “Would they fit the culture?”
A specific, testable question, such as:
Can this person independently own this problem in 90 days?
Can they make decisions with incomplete information?
Can they operate at our current pace without support?
If the interview is designed around one question, the output is simple.
“Yes” or “no”.
No meeting or debrief required.
| The real purpose of an interview
Most founders make the mistake of treating interviews as conversations (I know I’ve fallen into this trap many times!).
An interview should not be a discussion. Think of it as a measurement tool.
If you cannot clearly articulate what is being measured, you will get opinions instead of the signal you need.
Opinions force debriefs. Signal enables decisions.
| Replace debriefs with written evidence
One simple rule:
If feedback is not written down immediately after the interview, it should not count.
Written feedback does four things:
Forces precision
Preserves first impressions
Prevents groupthink
Exposes disagreement early
If two interviewers disagree, that is not a problem to be smoothed over or discussed.
It is a design flaw to be fixed.
| Why founders resist this
Debriefs feel safe and fall under the category of “everyone does this”, so everyone is comfortable defaulting to this practice
But safety and comfort are not the goal.
A clear outcome is.
| A quick test
Cast your mind back to your last hiring loop.
Could each interviewer answer the following, in writing, in one sentence?
“Based on what I observed, would I hire this person tomorrow for this role?”
If the answer required a meeting, the interview process is flawed.
| What this unlocks
When interviews are designed to produce clean signal:
Decisions speed up
Disagreement becomes useful
Debriefs disappear
Conviction increases
Hiring stops feeling heavy because it stops being vague.
In the next issue, we will look at the illusion founders rely on to feel objective.
Interview scores (they look precise…they’re not)
Cheers
