How should we run interviews for our next hire?

Compare a hiring manager deciding alone, a structured loop with an independent reviewer, and an asynchronous work-sample process — in interviewer hours, calendar weeks and safeguards.

The short answer

A structured loop takes about twice the person-hours of a manager-only process under the default inputs, in exchange for written criteria, evidence before discussion and a second opinion. Whether that improves who you hire is not something these numbers can show; a one-role pilot is the cheapest way to find out how it works for your team.

Who this is for Founders and managers at companies hiring a few people a year, who want a fairer, clearer decision without building an HR department.

Your situation

Optional. Answers decide which paths meet your hard constraints; "not sure" keeps a requirement unresolved instead of guessing.

  • Do at least two people besides the hiring manager have time to interview?
  • Is there someone outside the hiring team who could interview and question the final decision?
  • Can the role's work be sampled in a short task (a few hours at most)?
  • Would a wrong hire in this role be costly or slow to undo?

The paths

Your current approach, the alternatives and a smaller reversible pilot — all with the same inputs and horizon.

Current approach

Hiring manager decides alone

Original WeCaseStudy template

The hiring manager reads applications, runs two interviews per finalist and decides.

Setup effort
33 h
Ongoing effort
0 h / week
Cash over the horizon
$0
Reversibility
Nothing to unwind: this is the current process.

Main uncertainty: Decision quality rests on one person's judgment, attention and consistency on the day.

Alternative

Structured loop with an independent reviewer

WeCaseStudy adaptation for your context

Criteria fixed in a scorecard, sessions mapped to competencies, written feedback before the debrief, and one interviewer from outside the hiring team.

Setup effort
67 h
Ongoing effort
0 h / week
Cash over the horizon
$0
Reversibility
Drop the extra sessions or the reviewer for the next opening; the scorecard stays useful.

Main uncertainty: The sources describe the practice at a large company; they do not show that an independent reviewer improves hiring outcomes in a team of your size.

Alternative

Async work sample, then two interviews

WeCaseStudy adaptation for your context

Shortlisted candidates complete a short, realistic task in their own time; reviewers score it against the scorecard; finalists have two structured interviews.

Setup effort
47 h
Ongoing effort
0 h / week
Cash over the horizon
$0
Reversibility
Remove the task from the next opening.

Main uncertainty: How many candidates complete the task, and whether it predicts performance in your role, is unknown until you try it.

Smaller reversible pilot

Pilot: add structure to one opening

Original WeCaseStudy template

Keep the current process but add a scorecard and written feedback for one role, then compare with the last hire.

Setup effort
44.5 h
Ongoing effort
0 h / week
Cash over the horizon
$0
Reversibility
Stop after one role.

Main uncertainty: One hire is too few to judge outcomes; it can show effort and process quality only.

The comparison at default inputs

Person-hours are everyone's effort added up, not calendar time. Valued staff time is hours × the value of an hour: an economic cost, not a bill.

Steps in each path

Hiring manager decides alone (5)
  1. Write a short role description

    Hiring manager · weeks 1–1 · 2 h

  2. Review applications against the written criteria

    Hiring manager · weeks 2–2 · 8 h

  3. First calls with shortlisted candidates

    Hiring manager · weeks 3–4 · 10 h

  4. Interviews run by the hiring manager

    Hiring manager · weeks 5–6 · 12 h

  5. Decide and make the offer

    Hiring manager · weeks 7–7 · 1 h

Gains: One clear owner; Fewest people involved; Shortest calendar

Sacrifices: No independent check on the decision; Criteria stay in one person's head; Harder to compare candidates consistently

Must be true: The manager has the time to read every application properly; The manager can judge every skill the role needs

Structured loop with an independent reviewer (10)
  1. Write the role scorecard: outcomes and competencies

    Hiring manager · weeks 1–1 · 4 h

  2. Assign one competency and question set to each session

    Hiring manager · weeks 1–1 · 2 h

  3. Brief interviewers on the scorecard and feedback rules

    Interviewers · weeks 2–2 · 2 h

  4. Review applications against the written criteria

    Hiring manager · weeks 2–2 · 8 h

  5. First calls with shortlisted candidates

    Hiring manager · weeks 3–4 · 10 h

  6. Structured interview sessions

    Interviewers · weeks 5–6 · 24 h

  7. Independent reviewer interviews each finalist

    Independent reviewer · weeks 5–6 · 6 h

  8. Written feedback submitted before the debrief

    Interviewers · weeks 5–6 · 6 h

  9. Debrief: read feedback first, then discuss

    Interviewers · weeks 7–7 · 4 h

  10. Decide, record the reasons, make the offer

    Hiring manager · weeks 8–8 · 1 h

Gains: Shared, written criteria; Evidence recorded before group discussion; A second opinion from outside the team

Sacrifices: More person-hours per hire; One more week of calendar time; Scheduling across several people

Must be true: Interviewers will write feedback before they hear each other's views; The reviewer can say no without political cost

Async work sample, then two interviews (7)
  1. Write the role scorecard: outcomes and competencies

    Hiring manager · weeks 1–1 · 4 h

  2. Design a short, realistic work sample and its marking guide

    Hiring manager · weeks 1–1 · 4 h

  3. Review applications against the written criteria

    Hiring manager · weeks 2–2 · 8 h

  4. Review work samples against the scorecard

    Interviewers · weeks 3–4 · 15 h

  5. Two structured interviews per finalist

    Interviewers · weeks 5–5 · 12 h

  6. Written feedback submitted before the debrief

    Interviewers · weeks 5–5 · 3 h

  7. Decide, record the reasons, make the offer

    Hiring manager · weeks 6–6 · 1 h

Gains: Evidence from realistic work; Candidates choose when to do it; Fewer live sessions per finalist

Sacrifices: Candidates spend their own time on the task; Some candidates may drop out (the rate is unknown); Effort to design a fair task

Must be true: The task takes candidates no more than a few hours; Every sample is reviewed against the same criteria

Pilot: add structure to one opening (6)
  1. Write the role scorecard: outcomes and competencies

    Hiring manager · weeks 1–1 · 3 h

  2. Review applications against the written criteria

    Hiring manager · weeks 2–2 · 8 h

    Hiring manager · weeks 3–4 · 10 h

  4. Three structured interviews per finalist

    Interviewers · weeks 5–6 · 18 h

  5. Written feedback submitted before the debrief

    Interviewers · weeks 5–6 · 4.5 h

  6. Decide and record the reasons

    Hiring manager · weeks 7–7 · 1 h

Gains: Small, reversible change; Produces a scorecard you keep; Real data on interviewer time

Sacrifices: No independent reviewer yet; One role is a small sample

Must be true: There is a recent hire to compare with

About this decision

Most small teams hire the way they always have: the hiring manager reads the applications, talks to a few people and decides. It is fast and clear, and it puts every judgment in one head.

The alternatives on this page add structure in two different ways. A structured loop with an independent reviewer fixes the criteria before anyone meets a candidate, asks every interviewer to write feedback before the debrief, and adds one person from outside the hiring team. An asynchronous work sample replaces some live interviews with a short, realistic task reviewed against the same criteria.

The comparison counts person-hours (the effort of everyone involved) separately from elapsed weeks (how long the process takes). Parallel interviews do not reduce person-hours, and a faster calendar does not mean less work.

What this tool does not do. It does not score, rank or screen candidates, and it is not legal advice. Hiring is regulated in most places; check the rules that apply to the role and the location before you change your process.

When each path makes sense

  • Manager-only suits a first or second hire when the manager knows the work deeply, the role is easy to reverse, and speed matters more than a second opinion.
  • Structured loop with an independent reviewer suits roles that are hard to reverse (senior, customer-facing, leadership) and teams with at least two people who can interview.
  • Async work sample suits roles whose output can be sampled in a few hours — writing, design, analysis, code — and teams spread across time zones.
  • The one-role pilot suits anyone unsure: it adds a scorecard and written feedback to a single opening and compares it with the last hire.

When none of them fits

None of these paths fixes an unclear role. If you cannot write down what the person must achieve in their first six months, start with the role scorecard and stop there until you can. If the role is covered by specific legal or professional licensing requirements, use the process those rules require.
