As a Data Analyst at SGS TECHNICAL SERVICES PRIVATE, your daily routine will be dynamic and highly integrated with local laboratory and international business operations.

Your primary responsibility will be the extraction, transformation, and loading (ETL) of laboratory testing data, client operational metrics, or supply chain logs. You will spend a significant portion of your day validating this data against strict industry standards to ensure that no corrupted or inaccurate information makes its way into final client reports.

Collaboration is a cornerstone of this role. You will work closely with laboratory technicians, operations supervisors, and regional managers to understand their data needs. Rather than working in a silo, you will act as the analytical bridge, helping operations teams understand what the data says about their efficiency, equipment calibration, or product quality.

Additionally, you will design, build, and maintain operational dashboards and standard reports. These deliverables are used by both internal leadership and external clients to certify that products, materials, and systems meet international regulatory requirements.

To be competitive for the Data Analyst position, you should meet a combination of technical, academic, and interpersonal standards.

• Must-have skills:

  • Advanced proficiency in Microsoft Excel (data validation, complex formulas, pivot tables).
  • Strong logical reasoning and quantitative problem-solving skills.
  • Professional fluency in English (both written and spoken) for cross-border collaboration.
  • Prior experience in data management, reporting, or an analytical support role.

• Nice-to-have skills:

  • Proficiency in SQL, Power BI, or Python for data manipulation.
  • Active professional registration relevant to the domain (e.g., an active CRQ for chemical analysis roles in Brazil).
  • A background or degree in Chemistry, Biotechnology, Engineering, or a related scientific field.

Q: How technical is the Excel test during the interview process? A: The Excel test is frequently described by candidates as challenging and intermediate-to-advanced. It goes beyond simple formatting and basic formulas, requiring you to demonstrate speed, accuracy, and comfort with nested functions, data cleaning, and complex lookups under a strict time limit.

Q: Is English mandatory for all Data Analyst roles at SGS? A: Yes, English is highly prioritized because SGS is a prominent multinational corporation. You should expect at least one portion of the interview process—whether a written test, a reading comprehension exercise, or a conversation with a manager—to be conducted in English.

Q: What is the company culture like during the interview process? A: Candidates consistently report a very human, welcoming, and relaxed interview atmosphere. The recruiters and hiring managers make a deliberate effort to reduce psychological pressure, focusing on open, conversational dialogue rather than stressful interrogation.

Q: How long does the entire hiring process typically take? A: The process is generally very agile, often taking between one to three weeks from the initial application to the final decision. In cases where the hiring team has an immediate operational vacancy, multiple interview rounds may even be consolidated into a single day.

• Prepare your professional narrative in English: Be ready to discuss your previous experience, achievements, and career goals in English without hesitation. Practice summarizing your resume concisely.
• Understand the specific business unit: SGS operates across many sectors (minerals, agriculture, life sciences, systems certification). Research which business unit you are interviewing for and tailor your preparation to their specific data types (e.g., lab test results vs. logistics metrics).
• Brush up on basic logical reasoning: If your process includes online cognitive testing, practice timed logical puzzles beforehand to get comfortable with the pacing and format.

• Highlight your attention to detail: Since SGS is a testing and certification firm, a single data error can have massive regulatory consequences. Emphasize your personal strategies for auditing your own work and maintaining flawless data quality.
