UI/UX Designer Interview Questions India 2026

Tip: UX: the overall feel of using a product — is it useful, usable, enjoyable? Covers research, information architecture, interaction design. UI: the visual layer — typography, colour, spacing, icons. Great UX with poor UI is ugly but functional; great UI with poor UX is beautiful but frustrating.

Tip: Key principles: size (larger = more important), contrast (colour/value difference draws the eye), proximity (related items grouped), alignment (creates structure), repetition (consistency). The user's eye should move predictably through the layout.

Tip: A persona is a fictional but research-based profile of a target user. Create from: user interviews, analytics data, field observations. Include: name, goals, pain points, tech comfort, a quote. Say 'Priya would not understand this icon' in design reviews.

Tip: Wireframe: low-fidelity structural layout in grayscale. Mockup: high-fidelity static design with real colours, typography, and assets. Prototype: interactive simulation of the product. Use wireframes for layout decisions, mockups for visual sign-off, prototypes for usability testing.

Tip: Steps: define research questions, recruit 5-8 participants, create scenario-based tasks, facilitate non-leading think-aloud sessions, observe and record, affinity diagram to cluster findings, prioritise issues by frequency x severity. 5 users typically reveal 85% of usability problems.

Tip: Key checks: colour contrast ratio >= 4.5:1 (normal text), all interactive elements reachable via keyboard, images have alt text, form labels are associated with inputs, error messages are descriptive, focus states are visible. Test with a screen reader (VoiceOver).

Tip: Cognitive walkthrough: expert evaluation where evaluators step through tasks asking "will users know what to do here?" No real users needed — fast and cheap. Usability testing uses real users — more external validity. Both are complementary.

Tip: Show depth: describe the user problem, the constraint (technical, time, stakeholder), the solution you chose, and specifically what you gave up. "We simplified the power-user workflow to reduce onboarding friction for new users" shows product thinking.

Tip: Do not defend the design — understand the constraint. Ask specifically what is expensive: the animation? The layout? The custom component? Often a small design change eliminates 80% of the engineering cost. Collaborate, do not capitulate.

Tip: Day 1: analyse existing data (drop-off points, session recordings, 3 quick user calls). Identify the single biggest friction point. Define the aha moment. Day 2: sketch 2-3 concepts for that one bottleneck, prototype the best one in Figma. Focus: solve one problem well.

Tip: An affinity diagram organises qualitative data into themes by grouping related observations on sticky notes. Used after user interviews or usability tests. Process: write one observation per note, cluster, name clusters, prioritise.

Tip: Show a process, not just a toolset: Brief, Research (user interviews, competitive analysis), Define (persona, jobs-to-be-done), Ideate (sketches), Design (wireframes to mockups), Prototype, Test (usability testing), Iterate, Handoff (Figma specs, design tokens). Name tools at each stage.
