Interview scorecard template

Digital Workspace Acoustics Engineer interview scorecard

Evaluate Digital Workspace Acoustics Engineer candidates across 4 weighted areas: technical depth, work that shipped, diagnosis under uncertainty, and working across the org. Technical depth leads at 35%, so check command of open plan metrics: distraction distance and spatial decay per ISO 3382-3, NC/RC background curves, STI/STIPA, absorption coefficients and NRC ratings. Use the rubric to compare role-specific evidence consistently.

TL;DR
For technical depth, look for evidence the candidate quotes target rD and D2,S values, distinguishes NRC from Sabine absorption, and links NC curves to conferencing microphone pickup. For work that shipped, look for evidence the candidate names specific fit-outs, cites measured reverberation and privacy index improvements, and shows masking tuning curves signed off by the client. 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

Check command of open plan metrics: distraction distance and spatial decay per ISO 3382-3, NC/RC background curves, STI/STIPA, absorption coefficients and NRC ratings for ceiling and screen products.

Evidence to listen for

  • Explains the physics or mechanism behind their work, not just the tooling
  • Names the standards, tolerances, and constraints they designed against
  • Can defend a design decision under follow-up questions
  • Distinguishes what they personally engineered from what the team delivered

Five-point scoring guide

1
Poor

Cannot explain the fundamentals of their own stated specialism.

2
Needs Improvement

Knows the vocabulary but not the underlying mechanism; struggles under follow-ups.

3
Satisfactory

Solid working knowledge for the role; depth thins out on edge cases.

4
Very Good

Strong command of the domain; explains trade-offs and defends decisions well.

5
Excellent

Quotes target rD and D2,S values, distinguishes NRC from Sabine absorption, and links NC curves to conferencing microphone pickup.

02
Evaluation factor

Work that shipped

30% weight

Probe delivered workspace projects: huddle rooms, Teams or Zoom certified rooms, sound masking commissioning with LogiSon or Biamp, WELL sound feature credits, before and after measured results.

Evidence to listen for

  • Names specific programmes, parts, or systems that reached production or field use
  • States their own scope inside the project
  • Can give measured outcomes: yield, cycle time, cost, failure rate
  • Explains what went wrong and what they changed

Five-point scoring guide

1
Poor

No delivered work; experience is coursework, lab-only, or purely observational.

2
Needs Improvement

Contributed to projects but cannot say what shipped or what their part was.

3
Satisfactory

Has delivered real work; outcomes described without numbers.

4
Very Good

Names shipped work and their scope, with some measured results.

5
Excellent

Names specific fit-outs, cites measured reverberation and privacy index improvements, and shows masking tuning curves signed off by the client.

03
Evaluation factor

Diagnosis under uncertainty

20% weight

Test how they chase complaints with no obvious cause: HVAC tonal noise, flanking through plenums, echo on far-end calls, floor vibration from gyms or plant.

Evidence to listen for

  • Describes a real failure they chased to root cause
  • Shows a method: isolate variables, reproduce, measure, eliminate
  • Distinguishes correlation from cause
  • Says what they ruled out and why, not only what the answer turned out to be

Five-point scoring guide

1
Poor

No diagnostic method; guesses or escalates immediately.

2
Needs Improvement

Trial and error with no structure; cannot explain how they narrowed the cause.

3
Satisfactory

Reasonable method on familiar problems; less structured on novel ones.

4
Very Good

Clear systematic approach with a real root-cause story.

5
Excellent

Describes structured narrowing using narrowband spectra, intensity or accelerometer data, and near/far-end call recordings before proposing a fix.

04
Evaluation factor

Working across the org

15% weight

Assess dealings with architects, AV integrators, facilities and workplace strategy teams when acoustic treatment conflicts with exposed slab aesthetics or budget cuts.

Evidence to listen for

  • Explains technical constraints to non-technical stakeholders without condescension
  • Has negotiated scope, cost, or timeline with manufacturing, product, or suppliers
  • Documents decisions so others can act on them
  • Takes review feedback without defensiveness

Five-point scoring guide

1
Poor

Cannot communicate outside their specialism; dismissive of other functions.

2
Needs Improvement

Communication gaps cause rework; avoids stakeholder contact.

3
Satisfactory

Works adequately with other teams; documentation is thin.

4
Very Good

Communicates clearly across functions; reliable collaborator.

5
Excellent

Recounts trade-offs negotiated with named disciplines, offering alternative treatment options with cost and performance consequences stated plainly.
