Why pre-screen olfactory design consultants before the portfolio review
Scent is the one design element people cannot look away from. In a shop or a workplace it reaches staff who are there all day, some of whom have asthma or migraine, and the regulatory position on allergens is stricter than most clients realise. Consultants worth hiring raise that before the brief does. A short screen asks how they handle people who react badly.
What actually matters when screening Olfactory Design Consultant candidates
- 01
Portfolio
Review named scent programmes: hotel lobbies, retail flagships, museum installations. Ask for brief, chosen accords, diffusion hardware, coverage volume, and any lift in dwell time or recall.
- 02
Craft and rationale
Probe compositional vocabulary: top, heart and base structure, materials such as iso E super or ambroxan, headspace capture, and how they brief a perfumer at IFF or Givaudan.
- 03
Feedback and iteration
Test how they handle scent rejection: hedonic panel results, staff complaints about intensity, sensory fatigue, and reformulation rounds with the fragrance house before sign-off.
- 04
Working with the brief
Assess constraint handling: IFRA standards and allergen declaration, HVAC versus standalone diffusers, air changes per hour, budget per cubic metre, and multi-site rollout logistics.
Pre-screening questions to ask Olfactory Design Consultant candidates
12 questions grouped by what they test. Ask the same set in every screen and score answers on a consistent scale, or send them as an async video screen and compare answers side by side.
Work that shipped
3 questions01Can you describe a project where you delivered a scent into a product or space?
Listen forAn installed or launched project with the brief, the solution and the outcome described.
Concept work only, or projects that never reached installation or production.
02Do you have experience creating scent profiles for brands or products?
Listen forCommercial work with brands named where possible, and the brief translated into a specification.
Personal blending presented as commercial work, or no brief they had to satisfy.
03What experience do you have designing for different contexts such as retail or events?
Listen forDifferent settings handled with dwell time, ventilation and staff exposure all considered.
One approach applied everywhere, or space volume and airflow never considered.
Materials understood
4 questions04What is your knowledge of aromatic materials and their properties?
Listen forMaterials known by their behaviour, including volatility, longevity and declared allergen content.
Materials described by association alone, or allergen restrictions unfamiliar.
05Have you had to match or recreate an existing scent?
Listen forAnalytical and sensory approaches both used, with an honest account of how close they got.
Matching claimed as straightforward, or no method beyond trial and error.
06What is your experience working with fragrance houses and suppliers?
Listen forEstablished relationships with briefs written so a perfumer can work from them.
No supply chain experience, or briefs described only in emotional language.
07Have you worked on reducing or removing unwanted odours?
Listen forThe source identified and addressed rather than masked, with ventilation always considered first.
Masking used as the default solution, or the odour source never investigated.
Tested properly
3 questions08How do you test and evaluate whether a scent design works?
Listen forTesting in the real environment with staff and visitors, at the intensity actually used.
Evaluation done on blotters only, or intensity never checked in the finished space.
09How do you refine a scent based on feedback?
Listen forFeedback gathered from occupants as well as clients, with intensity adjusted after installation.
Feedback taken from the client alone, or systems left at the original setting indefinitely.
10How do you develop a scent for a particular audience?
Listen forCultural and demographic differences tested locally rather than assumed from general associations.
Audience preferences assumed, or the same profile applied across very different markets.
Honest claims
2 questions11How familiar are you with the physiological effects of specific scents?
Listen forEvidence described accurately, including how weak and context-dependent most of it is.
Specific mood or productivity outcomes promised, or sensitivities and asthma not mentioned.
12How do you work with architects, product designers and brand teams?
Listen forInvolvement early enough to affect ventilation and materials rather than added at the end.
Brought in after fit-out, or diffusion equipment installed without services coordination.
How to score responses
Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.
Portfolio
35%5Walks through three or more delivered scent identities with the brand brief, accord choices, hardware specified, and measured customer or client response.
Craft and rationale
25%5Names specific materials and accords, explains structure and substantivity choices, and translates a brand attribute into a defensible olfactory rationale.
Feedback and iteration
25%5Describes structured evaluation panels, tracks intensity settings and modification requests, and shows a scent that improved measurably across iterations.
Working with the brief
15%5Converts vague brand language into a workable brief with compliance limits, hardware spec, coverage calculations, and per-site cost clearly stated.
Staff cannot leave the scent you install. A one-way video screen asks how they handle adverse reactions.

Process basics
How long should a pre-screening round for this role take?
Ten to fifteen minutes across eight to ten questions, answered async. Enough to establish work that shipped, test their material knowledge, and hear how they handle testing and safety.
What should I ask for besides the screen?
References from installations still running a year later, and the specification documents. Both show whether the work survived contact with maintenance budgets and staff complaints.
Evaluating answers
What is the strongest signal when screening this role?
How they handle adverse reactions. Consultants who have installed real systems describe intensity control, ventilation and scent-free areas. Anyone who has not considered it will cause complaints.
How should I treat claims about mood and behaviour?
Sceptically. The evidence for specific scents producing specific effects is weak and heavily context-dependent. A consultant who cites studies with their limitations is more trustworthy than one who promises outcomes.
