As a UX/UI Designer at Alten Spain, you are stepping into a dynamic, highly collaborative consulting environment. Alten Spain partners with top-tier clients across industries like telecommunications, finance, automotive, and energy, meaning your work will directly shape digital products used by millions. You are not just designing interfaces; you are solving complex business problems through user-centered methodologies and elevating the digital footprint of major enterprise clients.

This position requires a unique blend of creative vision, technical proficiency, and consulting acumen. Because you will often be embedded within client teams, your impact extends beyond Figma canvases. You will act as a design advocate, guiding stakeholders through the design thinking process, justifying your decisions with data, and ensuring that the final product aligns with both user needs and the client's strategic goals.

What makes this role particularly exciting at Alten Spain is the sheer variety of challenges you will face. One project might involve overhauling a legacy banking dashboard, while the next could have you designing an intuitive interface for an automotive infotainment system. You can expect a fast-paced, rewarding environment where adaptability and strong communication skills are just as critical as your eye for aesthetics.

While the exact questions will vary based on the specific client project you are being considered for, the following patterns frequently appear in Alten Spain interviews.

Background and Experience

These questions usually occur during the initial HR phone screen to assess your baseline qualifications and communication style.

• Tell me about your background and how you got into UX/UI design.
• Walk me through your resume and highlight the projects most relevant to this position.

Preparing for an interview at Alten Spain requires you to balance your technical design portfolio with your ability to act as a consultant. Interviewers want to see how you think, how you communicate, and how you handle client feedback. Focus your preparation on the following key evaluation criteria:

Portfolio and Design Approach Your portfolio is your strongest asset. Interviewers will evaluate not just the final visual polish, but the journey you took to get there. You can demonstrate strength here by clearly articulating your research methods, wireframing processes, and how you iterate based on user testing and constraints.

Client Communication and Presentation Because Alten Spain is a consulting firm, you will frequently present your work to external stakeholders. Interviewers evaluate your ability to explain complex design concepts to non-designers. You must show that you can confidently defend your design decisions while remaining open to constructive feedback.

Adaptability and Problem-Solving Consultants must quickly integrate into new teams and understand unfamiliar industries. You will be assessed on how you approach ambiguous problems and structure your design process when requirements are unclear. Highlighting past experiences where you successfully navigated shifting project scopes will serve you well.

Language Proficiency Since many projects involve international teams or global clients, English proficiency is heavily evaluated. You must be prepared to seamlessly transition between Spanish and English during your interviews, demonstrating that you can conduct workshops and present deliverables in both languages.

The interview process for a UX/UI Designer at Alten Spain is generally described by candidates as positive, conversational, and straightforward. The evaluation is designed to be thorough without being overly stressful, focusing more on your practical experience and cultural fit than on high-pressure whiteboarding.

Your journey typically begins with a relaxed phone screening with an HR recruiter. This initial call focuses heavily on your work history, the specific projects you have participated in, your English proficiency, and aligning your expectations with the open vacancy. If you move forward, you will face a technical interview with a senior designer or design lead, where you will dive deep into your portfolio and methodology.

Because you will be working on client projects, the process also includes an evaluative design test to analyze your practical skills and design approach. Finally, you will have a meeting directly with the client company you will be assigned to, followed by an economic proposal from Alten Spain. This client meeting is crucial, as it ensures both technical alignment and interpersonal chemistry before an offer is extended.

This visual timeline outlines the typical progression from the initial HR screening through the technical evaluations, the design test, and the final client alignment meeting. Use this timeline to pace your preparation, ensuring your portfolio is ready for the early stages and your presentation skills are sharpened for the final client interview. Note that the exact sequence of the design test and client meeting may occasionally swap depending on the specific client's urgency.

To succeed in the Alten Spain interview process, you must be prepared to demonstrate expertise across several core areas. Below is a detailed breakdown of what interviewers are looking for and how you can stand out.

Portfolio Walkthrough and Past Projects

Your past projects are the primary lens through which your capabilities are judged. Interviewers want to see a clear narrative connecting user problems to your design solutions. Strong performance here means moving beyond "what" you designed and focusing heavily on "why" you designed it.

Be ready to go over:

• End-to-end process – Explaining your role from initial discovery and user research to final handoff.
• Metrics and impact – Discussing how your designs improved user retention, task completion rates, or business revenue.
• Handling constraints – Describing times when technical limitations or tight deadlines forced you to pivot your design strategy.
• Advanced concepts (less common) – Integrating accessibility standards (WCAG) from the ground up, or building scalable design systems from scratch.

Example questions or scenarios:

• "Walk me through a project in your portfolio where you had to balance user needs with strict business constraints."
• "Describe a time when your design was pushed back by the engineering team. How did you resolve the conflict?"
• "Which project are you most proud of, and what was your specific contribution to the final deliverable?"

Technical Skills and Design Test

Alten Spain utilizes an evaluative test to see how you tackle a brief in real-time or as a take-home assignment. This area evaluates your mastery of industry-standard tools (like Figma) and your structural approach to a new problem. Strong candidates deliver clean, well-organized files and can rationally explain their typography, color, and layout choices.

Be ready to go over:

• Information architecture – Structuring complex information into intuitive navigation models.
• Interaction design – Creating logical flows and micro-interactions that enhance usability.
• Prototyping fidelity – Knowing when to use low-fidelity wireframes versus high-fidelity, clickable prototypes.
• Advanced concepts (less common) – Utilizing advanced Figma features like variables, complex auto-layout structures, and interactive components.

Example questions or scenarios:

• "How do you organize your Figma files and design assets so that other designers or developers can easily collaborate?"
• "Here is a brief for a new onboarding flow. Walk us through the first three steps you would take to tackle this."
• "Explain how you ensure your designs are responsive across multiple breakpoints."

Client Communication and Language Proficiency

As a consultant, your ability to manage stakeholders is just as important as your design skills. This area is heavily tested during the initial screen and the final client meeting. A strong performance involves active listening, clear articulation of ideas, and a high level of comfort speaking in English.

Be ready to go over:

• Stakeholder management – How you gather requirements, present updates, and manage expectations.
• Workshop facilitation – Your experience running discovery sessions or design sprints with non-technical clients.
• Feedback integration – How you handle subjective or conflicting feedback from multiple decision-makers.

Example questions or scenarios:

• "Tell me about a time you had to present a design concept to a client who did not understand UX principles."
• "Let's switch to English for a moment: Can you describe your daily routine in your current role?"
• "How do you handle a situation where the client insists on a feature that you know will harm the user experience?"

As a UX/UI Designer at Alten Spain, your day-to-day work is highly collaborative and project-driven. You will spend a significant portion of your time embedded within agile client teams, working alongside product managers, business analysts, and frontend developers to translate complex requirements into intuitive digital experiences. You are responsible for the entire design lifecycle, from initial user research and wireframing to high-fidelity prototyping and developer handoff.

A major part of your role involves active communication. You will regularly lead design reviews, present your concepts to client stakeholders, and justify your decisions using UX best practices and user data. You will also be tasked with creating and maintaining design systems to ensure visual consistency across large-scale enterprise applications.

Beyond design execution, you will act as a consultant. This means proactively identifying areas where the client's product can be improved, advocating for the end-user, and helping the client understand the value of a strong UX strategy. You will often juggle multiple deliverables, requiring excellent time management and the ability to adapt to the specific working culture of the client you are assigned to.

To be a competitive candidate for the UX/UI Designer position at Alten Spain, you must demonstrate a solid mix of technical design skills, consulting readiness, and language proficiency.

• Must-have skills – Mastery of Figma and modern design tools; a strong portfolio demonstrating end-to-end UX/UI processes; excellent English proficiency (B2/C1 minimum) for international client communication; experience working in Agile/Scrum environments.
• Experience level – Typically, candidates need 3+ years of experience in digital product design, ideally with some exposure to agency or consulting environments where client interaction was required.
• Soft skills – Exceptional presentation skills, stakeholder management, adaptability, and the ability to articulate the "why" behind design decisions clearly and confidently.
• Nice-to-have skills – Basic understanding of HTML/CSS to facilitate developer handoff; experience with specialized industries (e.g., fintech, automotive); familiarity with accessibility standards (WCAG) and usability testing platforms.
