How to Assess Engineering Managers: Interview Loop and Rubric
The engineering manager assessment problem
Most engineering manager loops are a senior engineer interview with a behavioral round bolted on. That is why so many EM hires fail in their first six months: the parts of the job that actually matter — running 1:1s, navigating a reorg, holding a struggling report accountable, pushing back on a VP — are not interviewed for at all.
The opposite failure mode is worse. Teams overcorrect and hire an EM who interviews beautifully on people topics but cannot read a pull request or push back on a bad technical decision. A few months in, the team is unhappy because the manager cannot help them ship.
You need an interview loop that tests both halves of the job and a rubric that grades them separately.
What an EM actually does
Before designing the loop, agree on what you are hiring for. The job decomposes into four skills, in roughly this order of how often they get the EM into trouble:
- People management. 1:1s, performance management, coaching, hiring, firing, career growth.
- Cross-functional execution. Translating ambiguous goals into shippable work, managing stakeholders, unblocking the team.
- Technical judgment. Reading code, weighing architecture trade-offs, knowing when to overrule an engineer and when to defer.
- Strategy and prioritization. Saying no, choosing what the team will not do, defending headcount.
The mix varies by level. A first-line EM with 4 reports needs (1) and (2) above all. A senior EM running multiple teams needs (3) and (4) more than they need to be running 1:1s.
The four-stage loop
Stage 1: Behavioral deep-dive (60 minutes, live)
The single highest-signal round. Run a structured behavioral interview with three or four narrow prompts that force the candidate into specific past situations:
- "Tell me about a report who was underperforming. Walk me through the first conversation, the plan you made together, and how it ended."
- "Tell me about a technical decision where you disagreed with your most senior engineer. What did you do?"
- "Tell me about a time a leader above you pushed for a deadline you thought was wrong. Step me through what you said and what happened."
Drill down. The first answer is usually generic ("we worked through it together"). Follow up: Which week did you decide to put them on a plan? What exactly did you write down? What did your skip say? If the candidate cannot get specific within two follow-ups, they are recounting someone else's story.
Use a scorecard with anchored levels per skill, filled in by the interviewer during the conversation, not after.
Stage 2: Live people-management simulation (45 minutes)
The behavioral round tells you what they did. The simulation tells you what they would do tomorrow. Two scenarios work well:
- The struggling report. "Here is a synthesis of three months of 1:1 notes for one of your reports. They were a strong hire, the last quarter has been a slide, and the team is starting to notice. Walk me through the next 1:1 you would run." Role-play the conversation; the interviewer plays the report.
- The interpersonal blowup. "Two of your reports had a tense disagreement in a design review. Both feel they were disrespected. Walk me through how you handle the next 48 hours."
Listen for: do they jump to a conclusion, or do they ask questions first? Do they go through HR mechanics on autopilot, or do they think about the human in front of them? Do they protect their team without absolving them?
This stage is uncomfortable for candidates who have only managed in calm waters. That is exactly the point.
Stage 3: Technical credibility (60 minutes)
EMs do not need to out-engineer their best engineer. They do need to:
- Read a non-trivial pull request and identify the riskiest part.
- Diagnose a production incident from a postmortem draft and ask the right questions.
- Make a small-system design call without hand-waving.
A useful format: hand the candidate a 200-line PR from your actual codebase (sanitized), a one-paragraph context, and ask them to do a live code review out loud for 25 minutes. Then run a 30-minute small system design conversation at the level of detail their reports work at, not a Big Tech "design Twitter" round.
If you are hiring an EM who will not write code, you can skip writing exercises entirely. You cannot skip code-reading and design judgment. An EM who cannot tell whether a senior IC's plan is sane will be steamrolled.
Stage 4: Strategy and prioritization (45 minutes)
Give the candidate a one-page document: a fictional team's current goals, headcount, in-flight projects, recent incidents, and a leadership request to add one more initiative. Ask them to walk you through:
- What they would say no to, and how they would say it to whom.
- What the team would and would not do next quarter.
- What signal they would track to know if the plan was working.
You are testing whether they can hold a real opinion under pressure, and whether they can sell it in a way that does not get them fired. Both are necessary.
The rubric
Score each stage independently across the four skills. A simple anchored rubric works:
| Skill | Below the bar | At the bar | Above the bar |
|---|---|---|---|
| People management | Avoids hard conversations; framings are vague | Runs structured 1:1s and PIPs; gives specific examples | Coaches reports through career inflection points; develops other managers |
| Cross-functional execution | Reactive; tracks tasks but not outcomes | Translates ambiguous goals into shippable plans; manages stakeholders | Anticipates blockers; resets unrealistic commitments without burning trust |
| Technical judgment | Defers to the loudest engineer; cannot read non-trivial code | Reads code and design docs critically; can pressure-test a plan | Drives architectural calls with senior ICs; knows when to overrule and when to defer |
| Strategy and prioritization | Says yes to everything; mistakes activity for impact | Picks 2–3 priorities; defends them with data | Reshapes the team's mandate when the strategy is wrong; defensible no's at exec level |
Calibrate before the loop runs, not after. Interviewer calibration on what "at the bar" means for your team is the single biggest lever you have to reduce hire-then-regret outcomes.
Common ways this loop goes wrong
- The hiring manager runs every round. You only hear yourself. Get an IC, a peer EM, and an exec on the loop.
- No one tests technical credibility. The team finds out the hire cannot follow a design review three weeks in.
- You hire on culture and storytelling. Every EM hire can tell a good story by their third loop. Anchor on the simulation and the rubric, not the vibes.
- You skip references. For EMs more than any other role, talk to two former reports, not just former managers. Former reports tell you what working for the person was actually like.
What to do next
If you are running an EM loop in the next month, write the rubric first, before you pick interviewers. Use it as the brief: every interviewer leaves with one or two anchored skills they are responsible for grading, not a vague "general impression" round.
