Getting Ready for Your Interviews

Preparing for an interview at Alten Delivery Centre Spain requires a strategic mindset. Your interviewers are not just evaluating your design skills; they are assessing how well you would represent Alten in front of their clients.

Focus your preparation on these key evaluation criteria:

Portfolio and Design Process Your interviewers want to see how you move from ambiguity to a polished product. They evaluate your ability to structure research, define user problems, and iterate on wireframes before arriving at high-fidelity designs. You can demonstrate strength here by clearly articulating the "why" behind every design decision in your case studies.

Client Communication and Stakeholder Management Because Alten operates on a consulting model, your ability to communicate effectively is paramount. Interviewers will assess your English proficiency and your capacity to explain complex design concepts to non-designers. Showcasing how you handle feedback and align differing stakeholder opinions will set you apart.

Technical and Tool Proficiency You must demonstrate a high level of comfort with industry-standard tools and design systems. Interviewers look for efficiency in tools like Figma, an understanding of responsive design, and a solid grasp of how your designs translate into front-end development constraints.

Adaptability and Problem-Solving Consulting requires flexibility. Evaluators want to know how you approach sudden changes in project scope or client requirements. You can prove this by sharing examples of how you have successfully navigated tight deadlines, ambiguous briefs, or shifting technical limitations.

Interview Process Overview

The interview process for a UX/UI Designer at Alten Delivery Centre Spain is generally described by candidates as straightforward and positive, focusing heavily on practical experience and cultural alignment. Unlike marathon tech interviews, Alten’s process is pragmatic. It typically begins with an initial phone screening conducted by HR or a recruiter. This conversation is designed to evaluate your baseline experience, English language proficiency, and general alignment with the open vacancy.

If you pass the initial screen, you will move into the core evaluation phases. This usually involves a technical and cognitive interview where you will discuss your past projects in depth. A defining feature of Alten’s process is the inclusion of an evaluative design test, which allows the team to analyze your hands-on competencies and project approach.

Because you will be working as a consultant, the final and most crucial step is often a direct interview with the client company you will be assigned to. This step ensures that both your technical skills and your working style align with the client’s specific needs and team dynamics.

The visual timeline above outlines the typical progression from the initial HR screening through the technical evaluations and the final client meeting. You should use this to pace your preparation—focusing on your narrative and English fluency for the early stages, deep-diving into your portfolio for the technical rounds, and preparing to discuss business value and collaboration for the client interview. Note that depending on the urgency of the client’s needs, these stages may be consolidated.

Deep Dive into Evaluation Areas

To succeed, you need to understand exactly what your interviewers are looking for during the technical and client-facing stages.

Portfolio Presentation and Case Studies

Your portfolio is the foundation of your technical evaluation. Interviewers at Alten do not just want to see beautiful interfaces; they want to understand the engine driving your design. They will evaluate your ability to tell a compelling story about a product's lifecycle. Strong performance here means confidently leading the room through a project, highlighting your specific contributions, and openly discussing what did not work and how you pivoted.

Be ready to go over:

• Problem Definition – How you identified the core user and business problems before designing.
• Research and Ideation – The methods you used to gather insights (e.g., user interviews, competitive analysis) and how they influenced your wireframes.
• Outcome and Metrics – How you measured the success of your design once it was implemented.
• Advanced concepts (less common) – Establishing design systems from scratch, conducting extensive accessibility audits, or integrating complex data visualization.

Example questions or scenarios:

• "Walk me through a project in your portfolio where you had to compromise on your ideal design due to technical constraints."
• "How did you validate the design decisions you made in this specific case study?"
• "Explain your role in this project—what exactly did you own versus what was collaborative?"

The Evaluative Design Test

Alten frequently utilizes an evaluative test or take-home assignment to analyze your practical skills and project approach. This stage matters because it strips away the polish of past work and shows how you handle a fresh, potentially ambiguous brief. Evaluators look for a structured methodology, clean file organization, and a clear rationale for your UI choices.

Be ready to go over:

• Requirement Analysis – How you break down the provided prompt and identify missing information.
• Information Architecture – Structuring the user flow logically before jumping into visuals.
• UI Execution – Typography, spacing, color theory, and adherence to standard UI patterns.
• Advanced concepts (less common) – Creating interactive, high-fidelity prototypes with complex variable states in Figma.

Example questions or scenarios:

• "Present the solution you created for the design test and explain your primary user flow."
• "Why did you choose this specific navigation pattern over alternatives?"
• "If you had an extra week to work on this test, what would you add or refine?"

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.

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.
