A UI designer interview can reveal useful judgement without asking applicants to redesign your live product for free. For an Islamabad company, start with the interface decisions the role will actually own: arranging information, explaining actions, handling states and working within a design system. Then use a fictional problem or a structured portfolio discussion to assess those decisions.
A polished screenshot is only one part of the evidence. The employer also needs to know how the designer understands a task, responds to constraints and communicates with the people who build the interface. Those skills can be discussed before requesting any new visual work.
Choose between portfolio review and a paid sample
Ask the candidate to show work they are permitted to share and explain their role. Who supplied the requirements, what did they decide and what changed after feedback? This is more informative than assuming every screen in a portfolio was independently conceived and produced by the applicant.
If a new sample is necessary, define a short paid exercise. State the compensation, time limit, deliverable and permitted use. Use fictional content rather than an active client requirement. Do not collect several usable redesigns under the label of an interview and leave ownership unclear.
A discussion or rough sketch may be enough when the question is reasoning. High-fidelity output is useful only if that level of execution is genuinely part of what you need to assess.
Build a workflow with a real decision
A fictional equipment-booking screen offers a manageable problem. Employees need to choose an item, see whether it is available and submit a request. Approval remains with a manager. Give the candidate the user goal and a few known constraints, then ask what they need to clarify.
| Interface state | Question for the designer |
|---|---|
| Item available | What information supports a sensible request? |
| Item unavailable | How can the user understand alternatives? |
| Required detail missing | How does the interface help correction? |
| Request submitted | Does the message distinguish requested from approved? |
The last state matters. A visually attractive confirmation that implies approval would misrepresent the process. Ask the candidate to explain how language and layout work together, rather than judging colour choices alone.
Look for a clear information hierarchy
Ask which details appear first and why. The candidate should connect prominence to the user's task. An equipment photograph may help identification, but it should not hide availability or the action required. Several layouts may be defensible if the reasoning is coherent.
Discuss the narrow-screen version. The designer need not produce a second complete design during a short interview, but should recognise how priorities change when space is limited. Ask what remains visible and what can move without making the task harder to understand.
Include relevant accessibility considerations in the brief and have a suitably qualified reviewer assess specialist requirements. The hiring conversation can reveal attention to labels, contrast and interaction states, but it should not be described as a complete accessibility certification.
Use critique to assess collaboration
Offer one concrete concern: “The submitted state looks the same as approval, and employees may think they can collect the item immediately.” Ask the candidate how they would investigate and revise it. Look for engagement with the underlying misunderstanding rather than defensive attachment to a visual treatment.
The candidate may suggest changing the wording, adding a status label or revising the next-step explanation. Discuss the tradeoffs. A different solution from the interviewer's first idea is not automatically wrong.
Do not introduce new business rules midway without acknowledging them. If the employer changes approval from manual to automatic, that is a requirement change. The candidate's response should be assessed as adaptation to new information, not a correction of an original mistake.
Ask what a developer would receive
A handover needs more than a final screen. Ask how the designer would explain states, component behaviour and unresolved questions. For the fictional booking flow, the developer needs to know what happens when availability changes or a required field is missing.
The expected detail depends on your team. A mature design system may already define common components; a new product may need more specification. Explain that context so candidates are not judged against an invisible standard.
Do not demand confidential source files from previous work. A candidate can describe a handover method or demonstrate it using the fictional exercise. Respecting those boundaries is compatible with a thorough assessment.
Make the job as clear as the exercise
State whether the Islamabad role includes research, visual design, prototyping or design-system maintenance. Identify the product decision maker and the development reviewer. A single vacancy should not quietly absorb every product discipline without support.
For technology-team hiring in Islamabad, describe the product and design responsibilities. Read the hiring process, candidate checks and pricing guide before arranging an assessment. Choose a designer whose decisions help users understand and complete the task, with evidence that matches the role rather than a free client deliverable.
