Technical & Analytical Skills

This category assesses your ability to work with data tools, write basic queries, and interpret quantitative information to solve business problems.

• Write a SQL query to find the second-highest transaction value from an operations database.
• How would you clean and prepare a messy dataset that has missing values and duplicate entries before presenting it to stakeholders?

Preparing for an interview at SLB requires a strategic approach that balances technical practice with behavioral storytelling. To stand out, you must demonstrate not just that you can perform data analysis, but that you understand the business implications of your findings.

Data-Driven Problem Solving – You must show a highly structured approach to solving ambiguous problems. Whether resolving a technical bottleneck or working through a guesstimate, walk your interviewer through your logic step-by-step, making reasonable, clearly stated assumptions.

Value Generation & Impact – SLB highly values candidates who focus on outcomes rather than just processes. When discussing your past projects, always highlight the quantitative impact—such as costs saved, hours reduced, or revenue generated—and support your claims with specific metrics.

Technical Competence – You need a strong grasp of foundational data tools, including SQL, Excel, and visualization platforms like Power BI or Tableau. Be prepared to explain how you apply these tools to real-world business datasets to extract meaningful insights.

Communication & Stakeholder Management – As a Business Analyst, you will act as a translator between technical teams and business leaders. Practice explaining complex technical concepts in simple, business-friendly terms, demonstrating strong active listening and confidence.

The interview process for the Business Analyst role at SLB is structured to evaluate both your technical capabilities and your behavioral fit over several stages. While the process is efficient and highly coordinated, candidates should expect a thorough assessment of their analytical and communication skills.

The journey typically begins with an online assessment designed to test your cognitive ability, logical reasoning, and technical foundations. Depending on the specific team and location, this may take the form of a HackerRank test containing multiple-choice analytical questions and a basic coding or SQL exercise, or a graded written technical test. Successful completion of this stage is followed by an initial screening call with HR to discuss your background, interest in the role, and basic career alignment.

Once through the initial screens, you will transition to the core interview rounds. This phase typically includes a deep-dive technical interview focusing on your resume, projects, and domain knowledge, where you may also be asked to solve a guesstimate or a business case study. Following this, you will meet with hiring managers and senior leadership for a managerial round focused on your strategic thinking, problem-solving methodology, and behavioral alignment with SLB's culture.

The visual timeline above outlines the typical progression from your initial application to the final offer stage. Candidates should use this timeline to pace their preparation, ensuring they dedicate sufficient time to technical practice before the initial test, while refining their project stories and behavioral answers ahead of the live interview rounds.

To succeed in the SLB interview process, you must understand the core competencies that interviewers are actively evaluating at each stage.
