Interviewing at Criteo
Criteo’s interview loop is heavily technical, with System Design, Python, and Algorithms appearing at very high prominence in the extracted question set, and Problem Solving also prominent. Across reported steps, you should expect a mix of coding and architecture discussions, plus an evaluation of your reasoning and communication rather than just getting to a single answer.
What they test most clearly is your ability to solve technical problems and explain your thinking: SQL and Python are both very prominent, while Coding Interviews, Algorithms, and Data Structures show up at high prominence. System Design is the most prominent topic by far, and Business Forecasting is also highly prominent, which matches the recurring case study theme of presenting findings.
After screening, you may move through case study presentation and multiple technical rounds, including coding screens and live or design-oriented system discussions. Candidate reports show that timelines can vary, sometimes clean and fast, sometimes stretching across weeks or even around two months, and multiple candidates reported no offer overall based on the aggregated offer rate.
System Design is the top-ranked topic, and case study presentation is also common, so you need both an architecture-ready narrative and a business-forecasting style explanation of your work.

The interview process, end to end
4 rounds · based on 508 candidate reports- 1Application review and recruiter screening
You start with an evaluation of your application and background, followed by an initial screening call. Reports describe recruiter or HR style conversations to assess fit and align on next steps.
- 2Technical screening and assessments
You may go through a coding and algorithms-focused technical screening, including online or live coding. Some candidates also reported timed technical assessments under strict proctoring constraints.
- 3Case study presentation and technical interviews
You may present a case study that demonstrates analytical skills, with a focus on business forecasting for relevant markets and an oral presentation of findings. Alongside this, interviews can include technical skills relevant to marketing analytics and system and architecture discussions.
- 4Onsite or team interviews plus behavioral interviews
You may have onsite interviews with multiple rounds and different team members, including coding exercises and system design discussions. Behavioral interviews assess cultural fit and collaboration skills, and team interviews involve communication and collaborative problem solving.

Do this
- Practice System Design with a focus on tradeoffs and clear communication. When you explain your architecture, tie your choices to how the system would behave, since the topics data heavily prioritizes Systems and Architecture.
- Do targeted preparation for forecasting-style questions. The topic set highlights Business Forecasting, and the process reports include case study presentations that culminate in an oral presentation of findings.
- Expect algorithmic questions and be ready to walk through your reasoning. Coding Interviews, Algorithms, and Data Structures are all high prominence, and at least some technical screenings are described as deeper than just solving once.
- If you get a timed or proctored technical assessment, rehearse your workflow under constraints. At least one report describes disabled copying, no external IDEs, and an exam-like environment with restrictions on AI and external help.
Avoid this
- Do not assume the process will stay stable once it starts. Multiple reports describe last-minute additions or changing logistics around live parts or take-home materials.
- Do not focus only on getting answers, since Problem Solving is prominent. Several reports emphasize discussion and reasoning, not just the final code or diagram.
- Do not ignore business context. Case study presentation and Business Forecasting both show up strongly, and one report set indicates an oral presentation component.
- Do not rely on a single predictable interview format. Candidate reports mention routes that felt “by the book” for some people, but others reported lack of structure or unpredictable sequencing.
Criteo interview FAQ
Answered from real candidate and workplace dataHow hard is the interview loop?
Across candidate reports, 16.8% of questions are easy, 59.8% are medium, 21.9% are hard, and 1.4% are very hard. The topic mix also suggests that System Design and coding are both heavily represented, with several topics rated very high prominence.
What are the biggest technical topics I should prioritize?
The most prominent topics in the extracted question data are System Design (highest), Python (very high), Algorithms (very high), and Coding Interviews (high). SQL is also prominent, and Business Forecasting is high, which lines up with case study presentation steps.
What does the process look like step by step?
Reported steps include initial screening (recruiter style), technical screenings and technical assessments, case study presentation, behavioral interviews, and onsite or team interviews. Several roles also report system design discussions and coding components within technical stages.
How long does it take, and is it consistent?
Timelines are not consistent across reports. Some candidates describe a smooth, fast flow, while others describe dragging timelines across weeks or around two months with periods of silence, plus last-minute changes in parts of the loop.
What is the offer rate from candidate reports?
The aggregated candidate report offer rate is 0.0%. Candidate sentiment is 62.6%, and some reports still describe the process as positive or well-run even when no offer was made.
Can I expect remote flexibility, or in-person onsite rounds?
Onsite Interviews are reported by roles, described as in-person interviews with multiple rounds and different team members. Some reports also mention strict office-day requirements despite talk of remote flexibility, but the only directly listed process step is the in-person onsite component.
