The questions below represent common themes encountered during the Extia interview process. While every interview is unique, you should prepare to demonstrate both your technical proficiency and your ability to navigate the collaborative, agile culture that defines our teams.

Experience and Professional Background

These questions focus on your career trajectory and your ability to articulate your value proposition to Extia interviewers.

• Walk us through your professional journey and why you are interested in a Business Analyst role at Extia.
• Can you describe a project where you acted as a bridge between technical teams and non-technical stakeholders?

Success at Extia depends on your ability to balance deep technical rigor with strong communication skills. Prepare by reviewing your past projects through the lens of business value—always explain the "why" behind the data you analyzed or the process you improved.

Role-related knowledge – You must demonstrate mastery of SQL and data modeling. Interviewers will look for your ability to explain complex concepts in simple terms, proving you can manage the needs of both technical and non-technical stakeholders.

Problem-solving ability – We look for candidates who don't just follow instructions but proactively identify bottlenecks. Be ready to walk through a real-world case study where you had to structure an ambiguous problem and define a clear path forward.

Communication and Stakeholder Management – As a consultant, your ability to influence is paramount. Focus on how you translate technical output into business-friendly insights and how you handle difficult feedback from project leads.

Cultural Alignment – Extia values transparency, creativity, and agility. Be prepared to discuss how you contribute to team knowledge sharing and how you maintain a positive, proactive attitude, even when project requirements shift.

The Extia interview process is designed to be transparent and reflective of our agile culture. You should expect a progression that moves from high-level cultural fit and experience evaluation to more specific technical assessments. The pace is generally responsive, and you will likely engage with both HR representatives and business leaders who want to ensure you are a strong match for their specific project needs.

This visual timeline illustrates the typical progression from your initial screening to technical validation and final discussions. Use this to manage your preparation energy: treat the initial screens as a chance to tell your story clearly, and reserve your deepest technical review for the middle stages where you will be asked to demonstrate your analytical skills.

Data & SQL Mastery

This is the core of your technical evaluation. You must demonstrate that you can move beyond simple queries to optimize data retrieval and model complex schemas.

• SQL proficiency – Advanced joins, subqueries, and window functions.
• Data modeling – Understanding how to structure data for reporting and performance.
• Data validation – How you ensure the integrity of your outputs.

As a Business Analyst at Extia, your day-to-day will be dynamic. You are the primary point of contact for translating business strategy into technical reality. You will spend significant time in meetings to gather requirements, followed by deep-work sessions where you query databases and build dashboards to visualize performance.

You will also be responsible for maintaining the Backlog and ensuring that User Stories are clear, concise, and ready for development. Collaboration is constant; you will work closely with Data Engineers to ensure the underlying architecture supports your business objectives, and you will present your findings directly to business leaders to guide their strategic decisions.

We look for candidates who combine a strong analytical foundation with the soft skills required for consulting.

• Must-have skills:

  • Advanced SQL skills and experience with modern data warehouses (e.g., BigQuery, Looker).
  • Proven ability to design and maintain dashboards using Power BI or Tableau.
  • Solid experience with Agile/Scrum methodologies and backlog management.
  • Excellent communication skills in French and English.

• Nice-to-have skills:

  • Experience in a consulting environment where you managed multiple stakeholders.
  • Familiarity with cloud-based data ecosystems.
  • Previous experience in a Data Analyst or Product Owner capacity.

Q: How long does the hiring process typically take? A: The process is generally efficient and transparent. From your first contact to a final decision, you can expect a timeline of a few weeks, depending on interview availability and project alignment.

Q: What is the interview difficulty level? A: Most candidates describe the process as accessible and friendly. While the technical questions require genuine knowledge, the focus is more on your ability to solve problems and fit into our culture than on "trick" questions.

Q: Is this role remote or hybrid? A: We offer a hybrid work model, typically including 2 days of remote work per week. This allows our teams to maintain flexibility while still fostering the strong, in-person collaboration that is central to our culture.

Q: What differentiates a successful candidate? A: Successful candidates are those who show curiosity and a genuine passion for "data storytelling." Beyond technical skills, we look for individuals who take initiative and are eager to share their knowledge within our Communities of Practice.

• Show your work: When answering behavioral questions, use the STAR method (Situation, Task, Action, Result) to keep your answers structured and impactful.
• Be authentic: Extia values personality and "feel good" energy. Don't be afraid to show your enthusiasm for the work you do.
• Prepare for the "Why": Always be ready to explain why you chose a specific tool or methodology over another. We value critical thinking over rote memorization.
