Doctolib UX/UI Designer interview questions & guide 2026

The questions below represent the patterns observed in recent Doctolib interview cycles. They are designed to assess your technical proficiency, your ability to think on your feet, and your alignment with the company’s collaborative culture.

Portfolio & Experience

These questions focus on your background, your design philosophy, and your ability to articulate your past contributions clearly.

• Please tell me about yourself.
• What is your previous experience?

Preparation at Doctolib should be centered on demonstrating your design process, not just the final output. You are expected to be a storyteller who can explain the "why" behind every pixel.

Design Rationalization – You must be able to articulate the reasoning behind your layout, color, and interaction choices. Interviewers look for your ability to connect design decisions to specific user needs or business goals.

System Thinking – Doctolib operates on a large scale. You will be evaluated on your ability to work within existing design systems and your capacity to think about how a change in one area of the product impacts the broader ecosystem.

Collaborative Problem-Solving – You will often work in cross-functional pods. Demonstrate your ability to accept feedback, iterate based on team input, and communicate effectively with non-designers like Product Managers and Engineers.

The Doctolib interview process is structured, rigorous, and highly professional. It typically spans four stages, beginning with an initial touchpoint with a recruiter to assess fit and introduce the company culture. As you progress, you will engage with hiring managers and potential teammates who will dive deep into your portfolio and your technical approach.

A defining characteristic of the Doctolib experience is the "live" case study. This is a high-pressure, 1.5-hour session where you are tasked with solving a specific design problem in real-time. You will be expected to present your work and defend your decisions to a panel. While this stage is demanding, it is designed to mirror the collaborative, fast-moving nature of the team's actual work.

This visual timeline illustrates the progression from initial screening to the final, high-stakes case study. Candidates should use this to pace their preparation, focusing on portfolio storytelling for early rounds and rapid-fire design execution for the live assessment.

Portfolio Review

This is your first chance to showcase your depth. The team wants to see a clear narrative regarding your process, the challenges you faced, and the outcomes of your work.

Be ready to go over:

• The "Why" – Focus on why you chose a particular solution over others.
• User Impact – Quantify or describe the positive impact your designs had on the end-user.

As a UX/UI Designer, your primary responsibility is to translate complex medical and administrative workflows into intuitive, clean, and accessible digital experiences. You will be deeply involved in the entire product lifecycle, from initial discovery and user research to final handoff and design quality assurance.

You will work closely with Product Managers to define product requirements and with Engineers to ensure the technical feasibility of your designs. A key part of your day-to-day will involve maintaining and contributing to the Doctolib design system, ensuring that all new features align with the company's established visual identity and interaction patterns. You will frequently present your work to cross-functional stakeholders, requiring you to communicate complex design logic clearly and persuasively.

A strong candidate for this role possesses a blend of high-level design strategy and hands-on execution skills.

• Must-have skills:
  • Proficiency in standard design tools (e.g., Figma, Sketch).
  • Strong understanding of design systems and component-based design.
  • Ability to articulate design decisions based on user data or research.
  • Experience working in a cross-functional, agile product team.
• Nice-to-have skills:
  • Experience in the health-tech or complex SaaS domain.
  • Familiarity with accessibility standards (WCAG).
  • Basic understanding of front-end constraints (HTML/CSS limitations).

Q: How difficult is the interview process? A: Candidates generally describe the process as challenging but fair. The live case study is often cited as the most difficult part, so prioritize your time-management skills.

Q: What is the best way to prepare for the live case study? A: Practice working under time constraints. Focus on being able to explain your design decisions quickly and clearly; the "why" is often more important to the interviewers than the visual polish.

Q: How long does the entire process take? A: While it can vary, many candidates report a timeline of about a month from the initial recruiter screen to the final decision.

Q: Is it important to know the product beforehand? A: Yes. Use the Doctolib platform as a patient or explore its features deeply. Having a strong opinion on what works and what could be improved in the current app is a significant advantage.

• Show your process: Do not just show the final high-fidelity designs. Include wireframes, user flows, and early sketches to show how you arrived at your solution.
• Be prepared for feedback: During the case study presentation, interviewers may push back on your ideas. View this as a test of your collaboration skills rather than a personal critique.
• Reference the guidelines: The most common reason for failure in the case study is ignoring existing design guidelines. Always check if a component already exists before creating a new one.

The UX/UI Designer role at Doctolib is an opportunity to contribute to a product that makes a tangible difference in the healthcare sector. By focusing on your ability to rationalize design choices, work within a structured design system, and communicate effectively in a team, you will position yourself as a top-tier candidate. Remember that your interviewers are looking for a teammate who is as thoughtful about the user experience as they are about the business context.
