The questions below represent the patterns and themes frequently encountered by candidates interviewing for design roles at Alten. While you may not be asked these exact questions, practicing them will help you build a flexible narrative around your experience and process.

Portfolio and Experience

These questions assess your past work, your specific contributions, and the tangible impact of your designs.

• Walk me through your portfolio. Which project are you most proud of and why?
• Can you describe a project where your design directly improved a key business metric?
• Tell me about a time you had to design for a highly complex or technical domain. How did you approach the research?
• Explain your typical design process from receiving a brief to final developer handoff.

Technical and Process

These questions dive into your tool proficiency, your understanding of design principles, and how you execute your work.

• How do you structure and organize your Figma files for a seamless developer handoff?
• Describe your experience working with and contributing to Design Systems.
• How do you ensure your designs are accessible to all users?
• What is your approach to designing for edge cases or error states?

Behavioral and Client Management

These questions evaluate your consulting mindset, communication skills, and ability to navigate difficult workplace dynamics.

• Tell me about a time you had to explain a complex UX decision to a stakeholder who had no design background.
• How do you handle situations where the client's timeline does not allow for proper user research?
• Describe a time you received harsh criticism on a design. How did you react and adapt?
• How do you adapt your working style when joining a new team or client environment?

Client Interaction and Consulting Fit

Because you will be embedded with or delivering to Alten’s clients, your soft skills are heavily scrutinized. This area evaluates your English proficiency, your professional maturity, and your ability to act as a trusted advisor. Strong candidates demonstrate empathy, active listening, and the ability to push back on bad ideas diplomatically.

Be ready to go over:

• Stakeholder Management – How you handle conflicting feedback from product managers, developers, and clients.
• Agile Collaboration – Your experience working in sprints and handing off designs to engineering teams.
• Adaptability – Your willingness to learn the client’s domain quickly, whether it is banking software or automotive dashboards.

Example questions or scenarios:

• "Tell me about a time a client or stakeholder strongly disagreed with your design. How did you resolve it?"
• "How do you ensure that developers build exactly what you have designed?"
• "Describe your process for onboarding onto a completely new project in an unfamiliar industry."

Key Responsibilities

As a UX/UI Designer at Alten Delivery Centre Spain, your day-to-day work is highly dependent on the specific client project you are assigned to, but the core responsibilities remain consistent. You will be tasked with gathering and translating complex business requirements into user flows, wireframes, and high-fidelity interactive prototypes. You will spend a significant portion of your time in tools like Figma, conceptualizing interfaces that balance aesthetic appeal with functional usability.

Collaboration is a massive part of your daily routine. You will frequently partner with client-side Product Owners to refine user stories and define acceptance criteria. Simultaneously, you will work closely with front-end developers, conducting design hand-offs and performing visual QA to ensure the final coded product matches your vision. You are expected to be the bridge between the business's goals and the development team's execution.

Additionally, you will be responsible for presenting your work to various stakeholders. This involves preparing design rationales, leading review sessions, and sometimes conducting user testing to gather actionable feedback. Because you represent Alten, maintaining a high standard of professionalism, managing your time efficiently across Agile sprints, and proactively identifying areas for product improvement are essential parts of your role.

Role Requirements & Qualifications

To be competitive for this role, you need a balanced mix of technical execution and consultative soft skills. Alten looks for candidates who can hit the ground running on client projects.

• Must-have skills

  • Advanced proficiency in Figma (auto-layout, components, variables, and prototyping).
  • Strong command of the English language (both written and spoken) for daily client communication.
  • A solid portfolio demonstrating end-to-end UX/UI processes, not just visual design.
  • Deep understanding of responsive design principles and mobile-first methodologies.
  • Experience working in Agile/Scrum environments and collaborating directly with developers.

• Nice-to-have skills

  • Previous experience in a consulting firm or digital agency.
  • Familiarity with front-end frameworks (HTML/CSS, basic React or Angular constraints) to better communicate with engineers.
  • Experience creating or maintaining comprehensive Design Systems.
  • Knowledge of accessibility standards (WCAG).

• Experience level

  • Typically, candidates need 2 to 5+ years of professional experience in UX/UI design, depending on the seniority of the specific client request.

Frequently Asked Questions

Q: How difficult is the interview process? Candidates generally describe the Alten interview process as "easy" to "moderate." The focus is heavily placed on your practical portfolio experience and your communication skills, rather than trick questions or whiteboarding traps. If you know your process well and speak English fluently, you will navigate it smoothly.

Q: Why is there an interview with the client company? Because Alten is a consultancy, you are often hired to fulfill a specific need for an external client. The client interview is a mutual fit check to ensure your skills and personality align with the team you will actually be working with day-to-day.

Q: How much time should I spend on the evaluative design test? While instructions vary, it is best to timebox yourself to the recommended hours (usually 4-8 hours). Focus on showing a clear, logical process and a clean, well-organized final file rather than rushing to build dozens of screens. Quality and rationale matter more than sheer volume.

Q: What is the typical timeline from the first call to an offer? The process usually spans 2 to 4 weeks. The pace often depends on the availability of the external client for the final interview stage.

Q: Is the role remote, hybrid, or onsite? This heavily depends on the specific client assignment. While Alten supports flexible working models, some clients in sensitive sectors (like banking or automotive) may require a hybrid presence in the office. Clarify this during your initial HR screening.

Other General Tips

• Tailor your portfolio presentation: Do not just scroll through your website. Create a dedicated slide deck for your portfolio presentation that highlights the problem, your process, and the outcome. This shows strong presentation skills, which are vital for a consultant.
• Master the developer handoff narrative: Alten works heavily in engineering. Emphasize how you annotate your designs, use redlining, and communicate with developers. Showing that you are "developer-friendly" is a massive advantage.
• Practice your English terminology: Even if your general English is excellent, ensure you are comfortable discussing specific UX/UI terminology (e.g., heuristics, affordances, agile sprints, technical debt) fluidly in English.
• Ask questions about the client: During the interviews, ask about the client's design maturity, the size of their team, and their expectations. This demonstrates a proactive, consulting mindset.
