How we assess

Every applicant goes through 5 gates: application, an AI-assisted screen, a live technical assessment scored by a practice lead, a client-fit interview, and reference and credential checks. The questions below come from the live assessment. We score answers on reasoning and trade-offs, not on recalling definitions.

20 technical questions with model-answer hints

Questions 1–⁠10 (role-specific)

  1. Question 1: Walk us through a project where research changed your direction.

    Model-answer hint

    Specific evidence, what changed, impact; not a list of process steps.

  2. Question 2: How do you frame a vague request such as “redesign the dashboard”?

    Model-answer hint

    Asks who uses it, which decisions it supports and current metrics; problem statement before pixels.

  3. Question 3: How do you measure whether a design worked?

    Model-answer hint

    Success metrics agreed upfront, analytics, usability measures, qualitative feedback.

  4. Question 4: How do you work inside a design system you disagree with?

    Model-answer hint

    Uses it, documents gaps, proposes changes through the contribution model.

  5. Question 5: How do you design for Arabic and English at the same time?

    Model-answer hint

    Mirroring rules, typography pairing, text expansion, directional icons, testing with native readers.

  6. Question 6: Which WCAG 2.2 criteria affect your daily design work?

    Model-answer hint

    Contrast, target size, focus visible and not obscured, consistent help, accessible authentication.

  7. Question 7: How do you handle conflicting stakeholder feedback?

    Model-answer hint

    Returns to goals and evidence, tests alternatives, makes trade-offs explicit.

  8. Question 8: What does a good handoff contain?

    Model-answer hint

    Components, tokens, states, edge cases, responsive and RTL notes, presence during build.

  9. Question 9: Tell us about a design you shipped that failed.

    Model-answer hint

    Honest account, what was learned, what changed in their process.

  10. Question 10: Engineering capacity is cut in half. How do you re-plan?

    Model-answer hint

    Core user value, smallest testable slice, sequencing the rest.

Questions 11–⁠20 (Design core)

  1. Question 11: How do you decide what to research before designing?

    Model-answer hint

    biggest unknowns and riskiest assumptions first; method matched to the question and the timeline.

  2. Question 12: How do you turn research findings into design decisions?

    Model-answer hint

    synthesis into insights, prioritised opportunities, a traceable link from evidence to design.

  3. Question 13: How do you design for users with low digital literacy?

    Model-answer hint

    plain language, familiar patterns, fewer steps, forgiving inputs, testing with those users.

  4. Question 14: How do you design within strict regulatory or legal constraints?

    Model-answer hint

    involve compliance early, treat mandatory content as requirements, offer plain-language alternatives, record approvals.

  5. Question 15: How do you include people with disabilities in research and testing?

    Model-answer hint

    recruitment through partner organisations, assistive-technology set-ups, accessible materials, fair incentives.

  6. Question 16: How do you present design work to executives?

    Model-answer hint

    problem and goal first, options with trade-offs, evidence, a clear decision request.

  7. Question 17: How do you use generative AI tools in your workflow responsibly?

    Model-answer hint

    exploration and speed, human refinement, licensing and brand rules, no confidential data in prompts.

  8. Question 18: How do you design error states and edge cases?

    Model-answer hint

    list failure modes, give clear recovery guidance, preserve user input, test with real data.

  9. Question 19: How do you keep quality high when deadlines are tight?

    Model-answer hint

    protect critical journeys, reuse system components, agree what is deferred, record design debt.

  10. Question 20: How do you work with engineers while a feature is being built?

    Model-answer hint

    available for questions, reviews preview builds, pragmatic adjustments, shared ownership of quality.

Interviewer tip: Ask for a real example after every answer. Strong candidates describe what they built, what broke and what they changed.

Practical task

Timebox 3 hours. Redesign the onboarding flow of a provided bilingual banking app. Deliver a problem statement, a user flow, 4 key screens in English and Arabic built from the supplied component library, and a 1-page plan for testing the design with 5 users, including success metrics.

How to run it Share the brief 24 hours ahead or run it live. Ask the candidate to talk through trade-offs as they work; reasoning matters more than a finished artefact.

Red flags our practice leads watch for

  • Portfolio shows final visuals with no reasoning.
  • Designs in English only and “flips” for Arabic at the end.
  • Routinely detaches components instead of working with the system.
  • Cannot name a metric their work moved.
  • Universal flag: Vague answers that never reach a concrete system, number or decision the candidate personally owned.

The scorecard we use

Score each dimension 1–⁠4 (1 = no evidence, 2 = partial, 3 = solid, 4 = exceptional):

DimensionWeightWhat a 4 looks like
Technical depth, production judgement and security40%Explains how and why, designs for failure and sensitive data, and knows each tool’s limits
Practical task and problem solving30%Delivers a working solution with tests and documented decisions
Communication and documentation20%Explains clearly to technical and non-technical audiences, in English or Arabic
References and regional context10%References confirm the claimed scope; knows the frameworks and data-residency rules that apply

Pass bar: weighted average of 3.0 out of 4 or higher, with no dimension below 2. The practice lead approves the final result.

Every specialist on our shortlist has already passed this assessment. Working in 4 working days.

Frequently asked questions

Yes. The questions, hints, practical task and scorecard are free to use. They work best when every interviewer scores the same dimensions independently and compares notes afterwards. Ask for a concrete example after each answer, because recalled definitions say little about how someone performs on a live system.

They come from the same live technical assessment, but practice leads rotate and adapt questions so candidates cannot rehearse them. What stays fixed is the scope being tested, the practical task format and the scorecard, which is why the published version is safe to share.

Plan for a technical conversation covering 8 to 10 of the questions, plus the practical task either live or as a short take-home. Use the remaining questions as follow-ups. If you would rather skip the loop, Remote Pro Ai shortlists already-assessed specialists within 48 hours.

Our pass bar is a weighted average of 3.0 out of 4 or higher across the 4 dimensions, with no dimension below 2. Production judgement and security, scored inside the 40% technical dimension, often separate strong candidates from those who interview well but struggle once they own a live system.

The task mirrors the first week of real work in this role and never uses client data. It runs live or as a short take-home of a few hours, and the candidate then explains the trade-offs behind each decision. Reasoning and production habits count for more than a polished final artefact.
