Engineering Hiring Rubric

Engineering Hiring Rubric

Produce a complete hiring rubric and interview scorecard for evaluating software engineers at a specific role and level. The rubric must be specific enough that two interviewers who have never compared notes will score the same candidate within one level of each other. That requires: explicit behavioral anchors (what does "Strong Hire" look like vs. "Hire" for each competency), calibrated technical questions with written evaluation criteria, and a structured debrief format that surfaces signal rather than recency bias. Include calibration notes to help interviewers recognize and counter common evaluation biases.

Required Inputs

Ask for these if not already provided:

• Role — backend, frontend, fullstack, SRE/platform, data, ML, or mobile engineer
• Level — junior (L3/IC2), mid (L4/IC3), senior (L5/IC4), or staff (L6/IC5); clarify the company's level naming if different
• Team context — what the team builds, team size, and what problems this hire will work on in the first year
• Tech stack — primary languages and frameworks for the technical questions; list the stack explicitly
• Interview format — which rounds are used (phone screen, coding, system design, behavioral, take-home); if not specified, produce a recommended format

Output Format

Engineering Hiring Rubric: [Role] — [Level]

Role: [e.g., Senior Backend Engineer] Level equivalent: [e.g., L5 / IC4 / Senior] Team: [Team name and one-sentence description of what they build] Tech stack: [Languages and frameworks] Interview loop: [List the rounds in order]

1. Role Definition and Level Expectations

What This Role Does

[2–3 sentences describing the scope of work: what systems they'll own, what problems they'll solve, and who they'll work with. Make this specific to the team context provided.]

Level Bar

Define the minimum bar for a Hire recommendation at this level. This is not the ideal candidate description — it is the floor.

2. Interview Loop Structure

Interview coverage matrix: Each competency dimension must be assessed by at least 2 independent interviewers.

● = Primary signal ○ = Secondary signal

3. Coding Interview Guide

Question Selection

Choose 1–2 problems per coding round. Problems should be solvable in 30–40 minutes with the remaining time for discussion and follow-ups. Prefer problems with multiple solution tiers so you can see how far candidates take their thinking.

Problem Template

Problem: [Title]

Prompt (read to candidate):

[Problem statement — be specific. Include constraints (input size, value ranges). Avoid ambiguity that tests problem-reading rather than problem-solving.]

Example:

Given a list of integers representing stock prices at each minute of a trading day, return the maximum profit you could achieve by making exactly one buy and one sell. You may not sell before you buy.

Clarifying questions a strong candidate will ask:

• [e.g., "Can the list be empty?" / "Are all values positive?" / "Can profit be negative — i.e., should we return 0 if no profit is possible?"]

Solution tiers:

Follow-up questions:

• [e.g., "What if you could make at most k trades?"]
• [e.g., "How would you test this function? Write me 3 test cases."]
• [e.g., "Walk me through your code as if you're explaining it in a code review."]

4. System Design Interview Guide

[Level]-Appropriate Design Scope

At [Level], expect the candidate to:

• [e.g., Senior: "Design a complete system with capacity estimates, component breakdown, and discussion of failure modes"]
• [e.g., Mid: "Design the core components of a system; may need prompting on scalability and failure handling"]
• [e.g., Junior: "Design a simple client-server system; focus on clarity of thinking over complete distributed systems knowledge"]

Sample Design Question

Question: "Design [a URL shortener / a rate limiter / a notification service / a ride-matching system — choose one relevant to the team's domain]."

Evaluation dimensions:

Design Probing Questions

Use these to probe depth after the candidate presents their design:

• "Walk me through what happens when a write request comes in at peak load — 10,000 requests per second."
• "Your primary database just failed. What happens to the system?"
• "You estimated X QPS. How would your design change if it needed to handle 100× that?"
• "Where is the first place this system would fall over under load?"
• "How would you monitor this in production? What would your on-call runbook look like?"

5. Behavioral Interview Question Bank

Map every question to a competency. Ask 4–6 questions per behavioral round using STAR format (Situation, Task, Action, Result). Do not ask leading questions.

Competency: Ownership and Delivery

1. "Tell me about a time you owned something end-to-end — from design through production monitoring. What did you do when something went wrong after launch?"

   • Strong signal: Describes proactive monitoring setup, a specific incident they caught themselves, and what they changed
   • Weak signal: Describes writing the code and handing off; no discussion of production behavior

2. "Describe a project that was significantly delayed or failed. What was your role, and what did you take responsibility for?"

   • Strong signal: Direct ownership of their contribution to the failure; specific changes to how they work
   • Weak signal: Attributes all delay to external factors; no reflection on their own actions
