A Business Analyst at Roche operates at the intersection of life sciences, technology, and data-driven decision-making. In this role, you are not simply analyzing numbers; you are translating complex operational, financial, and clinical data into actionable insights that directly support Roche's mission of improving patient lives. Whether you are supporting diagnostics, pharmaceuticals, or corporate infrastructure, your work ensures that global teams can deliver therapies and medical solutions efficiently.

The impact of a Business Analyst is felt across the entire product lifecycle. You will collaborate with cross-functional stakeholders—including product managers, clinical researchers, IT specialists, and supply chain experts—to optimize workflows, design system architectures, and build robust reporting frameworks. The scale of Roche means you will tackle challenges of high complexity, requiring both deep analytical rigor and the ability to communicate technical findings to non-technical business leaders.

To succeed in this position, you must possess a unique blend of technical proficiency and business acumen. Roche values professionals who can navigate ambiguity, identify bottlenecks in legacy processes, and introduce modern, scalable data solutions. Your ability to influence decision-making through clear visualization and structured problem-solving is what makes this role both highly critical and intellectually rewarding.

The following questions represent patterns observed in real Roche interview experiences across various global offices. While the exact questions may vary depending on the specific business unit and location, preparing for these themes will ensure you are ready for the core evaluations.

Technical & Analytical Skills

This category assesses your hands-on capability with data manipulation tools, system fundamentals, and your logical approach to technical problem-solving.

• How would you write a SQL query to identify duplicate patient records across two disparate clinical databases?
• Explain how you would use advanced Excel functions, such as nested formulas or Power Query, to clean a messy dataset with missing values.

Preparing for an interview at Roche requires a balanced approach that demonstrates both your technical capability and your strategic alignment with the company’s values. You should focus on proving that you can translate raw data into strategic business value.

Role-related Knowledge – You must demonstrate a strong command of analytical tools such as Excel, SQL, and business intelligence platforms. Interviewers will evaluate your ability to select the right tool for the task and your understanding of data structures. Be prepared to discuss your technical workflow in detail.

Problem-solving Ability – Roche values candidates who approach challenges systematically. You should be able to break down ambiguous business problems into manageable components, formulate hypotheses, and design clear analytical frameworks to test them. Your thought process is often more important than arriving at a single "correct" answer.

Leadership & Communication – As a Business Analyst, you will act as a consultant to the business. You must show that you can present complex technical findings clearly and persuasively to senior leadership and cross-functional partners. This includes active listening, empathy, and the ability to drive consensus.

Culture Fit & Values – Roche operates in a highly collaborative, regulated, and purpose-driven environment. Interviewers will look for evidence of integrity, adaptability, and a genuine passion for contributing to healthcare. Showing respect for diverse perspectives and a commitment to continuous learning is essential.

The interview process for a Business Analyst at Roche is thorough and designed to evaluate both your technical proficiency and your behavioral alignment. While the process is highly professional and respectful, candidates should be prepared for a multi-stage journey that can span several weeks or even months, depending on the region and the complexity of the team.

The typical recruitment journey consists of several distinct phases, rising in seniority as you progress:

• Initial Recruiter Screen: A brief conversation with an HR representative or third-party recruiter to assess your background, motivation, and basic alignment with the role's requirements.
• Online Assessments & Technical Tests: Depending on the location, you may face an online test covering SQL, advanced Excel, logical reasoning, and aptitude. Some locations use negative marking, so accuracy is critical.
• Hiring Manager & Technical Round: A deeper dive into your technical skills, conceptual knowledge, and past project experience. You will discuss your analytical methodologies and situational judgment.
• Practical Case Study & Presentation: Many offices require you to complete a practical case study. This may involve a timed analysis (e.g., 2 hours to analyze a dataset and build a slide deck) followed by a presentation to an operational panel.
• Final Leadership Interview: A high-level discussion with senior directors or country managers to evaluate your strategic thinking, leadership potential, and long-term cultural fit.

This visual timeline maps out the typical progression from the initial recruiter screen to the final leadership round. Candidates should use this sequence to budget their preparation time, focusing first on core technical skills before moving to case presentation strategy. Note that while the sequence is standardized, the exact number of intermediate rounds may vary depending on your target business unit and geographic location.

To excel in the Roche interview process, you must understand exactly how you will be evaluated across the core competency areas.
