Interviewing at SLB
SLB interviews look like a pipeline that mixes recruiter or HR “fit” checks with multiple pruning technical stages. Across candidate reports and the extracted topic data, you should expect both timed or structured technical evaluation (coding, DSA, reasoning, and sometimes project or artifact based questions) and communication focused sessions such as interviews that emphasize how you explain your work.
What they actually test is consistent with the topic distribution: Python, algorithms and data structures, SQL, data analysis (EDA), predictive modeling, data preprocessing, and machine learning concepts show up at very high prominence in the collected question set. They also evaluate business analysis, accounting standards, and project or resume based technical interviewing, and they include communication as a prominent soft skill topic alongside problem solving.
In the reported process steps, you typically go through some combination of HR screening (initial or HR phone screening), group or collaborative exercises (group discussion or group discussion variant), online assessment and/or technical assessments, and one or more final rounds with technical leads and management. Timelines are described only qualitatively in the reports, with at least one “over a few weeks” flow, and multiple reports mention delays or lack of follow up even after early screens, so be ready for variable pacing after interviews.
Even when the early screen feels easy, multiple reports describe no clear next steps or silent delays, so treat every round as conditional and keep your preparation moving until you get explicit confirmation.

The interview process, end to end
6 rounds · based on 580 candidate reports- 1Initial screening call
You begin with an initial screening call to assess fit. Reports describe recruiter style conversations focused on your resume, motivation, background, and basic behavioral questions.
- 2HR screening call or HR phone screening
In some paths, you meet HR in an HR phone screening or HR screening call format. Reports describe a focus on your background, motivation to join, and basic behavioral questioning, sometimes with quick puzzles or an English check in certain accounts.
- 3Online assessment
You may complete an automated online assessment that tests cognitive ability, logical reasoning, mathematics, physics, and programming skills, sometimes including a HackerRank or written technical test. Candidate reports describe OA/DSA style exams with mixed easy and medium questions and sometimes Java centered coding.
- 4Technical assessments
You may face technical assessments that include coding challenges or discussions on research papers, sometimes via third party platforms. Reports describe timed coding, DSA and OOP style fundamentals, and project logic or system and deep project emphasis depending on the stage.
- 5Group discussion or group dynamics
You may participate in group discussion or collaborative exercises to test team work and communication style. Reports include group dynamics stages with monitoring and eliminatory aspects in some accounts, and extracted topics emphasize communication and problem solving.
- 6Final interviews and possible panel
Final rounds can include behavioral interviews, sessions with technical leads and management focused on domain expertise and cultural alignment, and possible final panel interviews. Reports describe technical panel rounds, deep project walkthroughs, and sessions where both technical and behavioral questions are intertwined, including strong emphasis on explaining real artifacts and engineering decisions.

What separates offers from rejections
Patterns from candidates who got offers, and the mistakes that most often sink a loop.
Do this
- Prepare to explain your projects in depth. Reports repeatedly describe deep project walkthroughs and technical panels that probe your understanding and the decisions you made.
- Make your technical reasoning audible. For DSA and coding, reports mention complexity analysis and correct approach, and the topic set heavily emphasizes problem solving and communication.
- Brush up on Python, SQL, and machine learning fundamentals. The extracted topic data shows Python programming, SQL, machine learning, predictive modeling, and data preprocessing as top prominence areas.
- Practice group participation and leadership signals. Reports describe group dynamics or eliminatory group discussions, and the extracted topics include communication and collaboration style.
Avoid this
- Don’t rely on “easy” early rounds as a guarantee. Candidate reports describe recruiter style conversations that felt easy but still ended with no offer and no follow up.
- Don’t give generic project summaries. Reports emphasize connecting your project story directly to the technical depth being assessed, including system design or detailed knowledge depending on the stage.
- Don’t underprepare on non-coding technical topics. The topic set includes accounting standards and business analysis alongside algorithms, SQL, and machine learning, so expect domain adjacent questions.
- Don’t neglect communication in technical and non-technical contexts. Communication and problem solving are prominent topics, and multiple reports connect outcomes to how clearly you explain and adapt.
SLB interview FAQ
Answered from real candidate and workplace dataWhat does the overall interview loop look like at SLB?
Based on reported process steps, you start with initial screening calls or HR phone screening, then you may do online assessments and technical assessments. You can also encounter group discussion or group discussion variants, and later rounds can include behavioral rounds plus final interviews with technical leads and management, and possibly a final panel.
How hard are the interviews, overall?
Difficulty in candidate reports is mostly medium (58.0%), followed by hard (20.6%) and easy (19.6%), with very hard at 1.8%. Reports also describe that difficulty varies by round, with some candidates seeing later technical stages as significantly harder.
What topics should I prioritize the most?
From the extracted question prominence, you should prioritize Python programming and algorithms and data structures (both at 100 percentile), plus machine learning concepts, behavioral interviewing, communication, business analysis, and data analysis (EDA), all at very high prominence. Also prioritize predictive modeling (97), SQL (95), and data preprocessing (95), and be ready for project or resume based technical interviewing (96) and LLM related questions (92).
Are there accounting or business domain questions?
Yes. Accounting standards questions appear at 96 percentile prominence, and business analysis appears at 100 percentile. Candidate reports also describe role specific domain probing depending on the path.
Do I get feedback or a clear next step after screening?
Not reliably. Multiple reports mention promised follow ups with no response, and some describe no offer and no further process update even after early recruiter style conversations.
What is the offer rate from candidate reports?
The aggregated offer rate from the 500 candidate reports is 0.0%, meaning the dataset did not capture any offers. Use this as a reminder that you should not assume later rounds will happen, and you should keep preparing for multiple technical pruning points.
