Candidates describe the Capgemini Data Scientist interview as applied rather than theoretical. The most repeated theme is project depth: several candidates say interviewers questioned them on feature engineering, metric choices, models used and deployment, and one says the questions stayed grounded in their resume, especially GenAI projects. Recent candidates also report GenAI questions, such as RAG architecture, handling hallucinations, and monitoring or drift for deployed models.
Fundamentals come up often. Reported questions include imbalanced data, overfitting, outliers, regression and classification metrics, bagging versus boosting, PCA and the bias-variance tradeoff. On the coding side, candidates mention Pandas, NumPy, SQL joins, Python lists, dictionaries and tuples, OOP and git basics. One candidate reports an online coding test with array and matrix problems, and another was asked what a data warehouse is.
The format varies. Some candidates describe an aptitude, English or gamified online assessment, while others describe a screening call, one or two technical rounds and an HR or manager conversation. Two candidates prepared something in advance: a shared case study in one process and an article presentation in another. One candidate had all rounds in a single day. Outcomes are mixed, including offers, rejections and a declined offer. One rejected candidate felt the expected depth on feature engineering workflows and evaluation metrics was higher than anticipated. Prepare concrete project stories that explain why you chose each tool and how you handled imbalance, outliers and overfitting. Revisit Python and SQL basics as well as ML.

Synthesized from candidate reports. Individual experiences may vary.
Several candidates report an online assessment or screening step before the interviews. Reports mention English, logical, quantitative and verbal aptitude, IT fundamentals, data science and coding questions, and in one case a gamified section with Sudoku and memory tasks. Not every candidate describes this step, so it may depend on the profile or the hiring cycle.
Candidates typically report an early conversation covering self-introduction, current responsibilities and general fit with the role and company culture. Have a concise summary of your background and recent projects ready.
Candidates report one or two technical rounds, ranging from about 40 minutes to 1.5 hours. Reported topics include feature engineering, metrics, imbalanced data, overfitting, Pandas, SQL joins, PCA and RAG or LLM work. Interviewers are generally described as friendly and focused on how candidates applied concepts in real projects.
Two candidates mention preparing something in advance: one discussed a pre-shared case study with a technical specialist, and another presented an article the company sent. This does not appear in most reports, so treat it as possible rather than standard. Be ready to explain your choices clearly and defend them.
Candidates commonly describe a final HR or manager discussion covering communication, teamwork and motivation, sometimes combined with a technical conversation. Outcomes reported include offers, rejections and a declined offer.
