Why pre-screen haptic designers before the technical panel
A haptic effect designed on one device feels weak on another and buzzy on a third, because actuator type, mounting and enclosure all change what reaches the hand. Meanwhile users can rarely say what is wrong beyond not liking it. Designers worth hiring tune per device and observe rather than ask. A short screen asks what they had to change between two devices, which demonstrations never show.
What actually matters when screening Haptic Interface Designer candidates
- 01
Technical depth
Probe fluency with LRA, ERM, piezo and voice coil actuators: resonance tuning, waveform authoring in tools like Immersion or TouchSense, and psychophysical thresholds such as JND.
- 02
Work that shipped
Ask for shipped devices carrying their haptic effects: phone taptics, automotive touch panels, VR controllers or surgical trainers, plus effect library size and latency budgets met.
- 03
Diagnosis under uncertainty
Test how they debug a buzzy or mushy effect: distinguishing driver clipping, mechanical coupling loss, enclosure damping or firmware timing jitter using accelerometer measurement.
- 04
Working across the org
Check collaboration with mechanical, firmware and UX teams on mass, mounting stiffness and gesture mapping, plus running user studies to validate tactile discriminability.
Pre-screening questions to ask Haptic Interface Designer 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.
Haptics that shipped
3 questions01Describe a project where you integrated haptic feedback into a product.
Listen forA product that shipped with the actuator type named, and their own contribution to the design described.
Demonstrations and prototypes only, or no product where the haptics reached real users.
02Can you talk about a time when haptic feedback improved a user experience?
Listen forA measurable improvement in task success or error rate, not just a claim that it felt better.
Improvement described as delight, with no behavioural evidence behind the claim.
03What experience do you have designing haptic feedback systems?
Listen forEffects designed and tuned by them, with the design intent for each effect stated clearly.
Effects selected from a library, or no design rationale behind the choices.
Tuned per actuator
3 questions04Can you explain the difference between force feedback and tactile feedback?
Listen forThe distinction understood with the hardware each requires, and where each is appropriate.
The two conflated, or hardware implications of each not understood.
05How do you work within hardware constraints when designing haptics?
Listen forActuator bandwidth, power and mounting treated as design inputs from the start.
Effects designed without knowing the actuator, or power budget never considered.
06How have you adapted haptic feedback across different hardware platforms?
Listen forEffects retuned per device with the perceptual difference described, not simply rescaled.
The same waveform shipped across devices, or differences assumed to be imperceptible.
Tested with people
3 questions07What user testing methods do you use for haptic interfaces?
Listen forComparison-based testing and behavioural measures, since users cannot easily describe a sensation directly.
Testing by asking users which they prefer, or no method beyond collecting verbal opinions.
08Describe your process for prototyping haptic interactions.
Listen forPrototyping on target hardware early, so effects are felt rather than specified on paper.
Effects specified in documents, or prototypes built only on development kits.
09What measures do you track to judge whether a haptic design works?
Listen forTask success, error rate and confusion measured, with false alerts and fatigue watched for.
Success measured by preference, or repeated exposure and fatigue never considered.
Accessibility considered
3 questions10What do you consider when designing haptic feedback for accessibility?
Listen forHaptics used to carry information for users who cannot see or hear a cue, with intensity adjustable.
Haptics used decoratively only, or no consideration of users with reduced tactile sensitivity.
11How do you test and calibrate haptics for consistency across devices?
Listen forMeasurement with instrumentation as well as by hand, with production variation accounted for.
Consistency judged by feel alone, or unit-to-unit variation never measured.
12How do you ensure the reliability and durability of haptic components?
Listen forActuator lifetime and drive limits respected, with degradation over the product life considered.
Actuators driven at their limit for effect, or lifetime not considered in the design.
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.
Technical depth
35%5Names actuator classes with drive requirements, cites resonant frequency tuning, and explains perceptual thresholds behind chosen amplitude and duration values.
Work that shipped
30%5Points to specific released products, describes their effect library and the sub-20ms latency and power targets the design had to satisfy.
Diagnosis under uncertainty
20%5Walks through isolating cause with accelerometer traces and swap tests, separating mechanical mounting problems from driver waveform or scheduling faults.
Working across the org
15%5Describes negotiating mounting and mass constraints with ME, aligning cues with UI states, and feeding user study results back into effect design.
The same waveform feels weak on one device and buzzy on another. A one-way video screen asks what they retuned.

Process basics
How long should a pre-screening round for this role take?
Fifteen minutes across eight to ten questions, answered async. Enough to establish shipped work, test their hardware understanding, and check how they run user testing for haptics.
How much hardware knowledge should I expect?
Enough to know how actuator type and mounting change the result. A designer working only in software will produce effects that feel right on their prototype and wrong in production.
Evaluating answers
What is the strongest signal when screening this role?
What changed between two devices. Designers with production experience describe retuning for a different actuator. Anyone whose effects transferred unchanged has worked on one platform.
How do I judge their user testing?
Ask how they test something users cannot describe. Real answers use comparison and behaviour rather than asking for opinions. Anyone relying on verbal feedback will get very little from it.
