Zero Trust Architecture Designer interview scorecard

Evaluate Zero Trust Architecture Designer candidates across 4 weighted areas: technical depth, real incidents and findings, risk judgement, and getting things fixed. Technical depth leads at 35%, so probe identity, segmentation, and policy enforcement depth, and whether they understand the protocols or only the vendor pitch. Use the rubric to compare role-specific evidence consistently.

TL;DR
For technical depth, look for evidence the candidate commands identity, segmentation, and policy enforcement at protocol level, independent of any vendor's framing. For real incidents and findings, look for evidence the candidate has run a real zero-trust migration, and is honest about what broke and what still relies on implicit trust. Apply the written 1–5 anchors to every answer, record the evidence behind each rating, and use the factor weights to reach a consistent overall assessment.

What to assess and how to score it

Review the evidence signals before interviewing. Then use the anchored descriptions—not instinct alone—to choose the score that best matches each answer.

01
Evaluation factor

Technical depth

35% weight

Probe identity, segmentation, and policy enforcement depth, and whether they understand the protocols or only the vendor pitch.

Evidence to listen for

  • Command of the specific attack surface, tooling, and controls the role covers
  • Understands how the underlying system works, not just how the tool reports on it
  • Can explain an attack or control chain end to end
  • Distinguishes what they found themselves from what a scanner flagged

Five-point scoring guide

1
Poor

Tool operator only; no understanding of the systems underneath.

2
Needs Improvement

Runs tooling but cannot explain findings or how the attack works.

3
Satisfactory

Solid working knowledge; depth thins outside familiar tooling.

4
Very Good

Strong command of the domain; explains attack and control chains clearly.

5
Excellent

Commands identity, segmentation, and policy enforcement at protocol level, independent of any vendor's framing.

02
Evaluation factor

Real incidents and findings

30% weight

Look for a migration they actually ran, not a diagram: what moved first, what broke, and what still runs on trust.

Evidence to listen for

  • Brings specific incidents, findings, or audits they personally worked
  • States their own role rather than the team's
  • Describes what was actually at risk and what changed afterwards
  • Can talk about a finding that turned out to be wrong

Five-point scoring guide

1
Poor

No hands-on work; knowledge is entirely certification or coursework.

2
Needs Improvement

Limited exposure; cannot describe their contribution to an incident.

3
Satisfactory

Real casework with adequate detail; ownership sometimes vague.

4
Very Good

Specific incidents with clear personal scope and what changed after.

5
Excellent

Has run a real zero-trust migration, and is honest about what broke and what still relies on implicit trust.

03
Evaluation factor

Risk judgement

20% weight

Test whether they can sequence a rollout that improves security without stopping the business on day one.

Evidence to listen for

  • Prioritises by actual exploitability and business impact, not raw severity scores
  • Can argue for accepting a risk as well as fixing it
  • Knows the difference between a finding and a problem
  • Does not cry wolf or wave things through

Five-point scoring guide

1
Poor

Treats every finding as critical, or waves real risk through.

2
Needs Improvement

Follows severity scores mechanically; no business context.

3
Satisfactory

Reasonable prioritisation; less confident arguing for risk acceptance.

4
Very Good

Prioritises by exploitability and impact; can justify accepting a risk.

5
Excellent

Sequences rollout by real exposure and can justify what they deliberately left until later.

04
Evaluation factor

Getting things fixed

15% weight

Assess how they get engineering and IT to adopt controls that make their daily work harder.

Evidence to listen for

  • Writes findings engineers can act on rather than a wall of output
  • Has persuaded a team to fix something they did not want to fix
  • Explains risk to executives in business terms
  • Works with the org rather than policing it

Five-point scoring guide

1
Poor

Adversarial with engineering; findings never get fixed.

2
Needs Improvement

Reports are unactionable; no influence beyond raising tickets.

3
Satisfactory

Adequate reporting; relies on mandate rather than persuasion.

4
Very Good

Actionable findings and a real record of getting fixes shipped.

5
Excellent

Wins adoption from engineering and IT by designing controls people can live with, with a record of what shipped.

Evidence-led prompts

Interview questions for a Zero Trust Architecture Designer
