Client-side versus server-side A/B testing
Client-side flickers and is bypassable; server-side assigns before response, hides logic, suits backend changes.
Recruiting channels for a B2C usability study
Compare panels for speed versus in-product intercepts for authenticity, weigh cost, screening rigor, and bias.
Turning a vague onboarding goal into research questions
Define success metrics, decompose the funnel, pair quantitative drop-off with qualitative why.
Why A/B-only, no upfront research, costs engineers more
A/B testing optimizes within a chosen direction but cannot reveal the right problem; building wrong wastes engineering cycles and tech debt.
Phased research strategy to de-risk market entry
Foundational market and behavior research, then localized usability and infrastructure validation, then iterative post-launch measurement, each feeding l10n, infra, and feature work.
Spec met but user problem unsolved: facilitating the fix
Frame requirements as the shared imperfect proxy, present evidence not opinions, and reframe as a joint discovery to refine.
Generative versus evaluative research in sprints
Generative explores problems before building and feeds requirements; evaluative tests solutions during and after build and feeds fixes.
NLP pipeline to theme and tag research transcripts
Chunk and embed transcripts, cluster or LLM-tag for themes, run sentiment with aspect awareness, and keep a human in the loop.
First technical questions to scope a journey-map pain point
Ask how widespread and severe it is, where in the system it originates, and what constraints bound a fix.
Confidence intervals versus p-values, explained simply
Define a CI as a plausible range for the true effect with its precision, contrast it with a binary p-value, and read [-1%, 7%] as inconclusive because it spans zero.
Diagnose and validate a failing usability task
Pinpoint the failure step from session and telemetry data, form a root-cause hypothesis, ship a targeted fix, and re-test to validate.
Build a compliant participant recruitment database
Capture granular, timestamped consent with lawful basis; minimize, encrypt, and retention-limit storage; and build self-service deletion that cascades.
Anonymization vs pseudonymization and key handling
Anonymization is irreversible and exits GDPR scope; pseudonymization is reversible via a separated key; secure that key in a KMS with strict access.
What is PII and how to keep it out of logs
Define PII, redact or mask at the logging boundary, and avoid logging sensitive fields at the source.
Aesthetics-Usability Effect
The aesthetics-usability effect is the tendency for users to perceive attractive designs as easier to use and to be more tolerant of minor usability problems in them, which can mask real issues during testing.
Data Visualization for Qualitative Data
Visualizing qualitative data turns coded themes, quotes, and patterns from interviews into affinity maps, theme matrices, and journey artifacts. It makes non-numeric findings scannable and persuasive without distorting nuance into false precision through…
Exposure Hours
Exposure hours measure the time each team member spends directly observing real users. Research by UIE found teams that watch users at least two hours every six weeks make markedly better design decisions, because firsthand empathy beats secondhand reports.
Mental Model Diagram
A mental model diagram aligns what users think and do, gathered from research, against what a product actually offers, exposing gaps where features are missing or unused so teams build for real behavior rather than assumptions.
Refactor a legacy UI for accessible DOM flow
Align DOM order with reading order, use semantic landmarks and headings, and ensure a sensible tab order with managed focus.
Manage light and dark themes with Variables and Modes
Separate primitive and semantic variables, define light and dark modes in one collection, and bind UI fills to semantic tokens.
We are hiring for this. Every open role lists the topics its interview covers, so you can prepare for the real thing rather than guessing.
