Candidates describe the Quantium Data Analyst interview as a mix of analytical testing and a serious look at motivation. Most accounts open with an online quiz or assessment. One candidate said the last question asked why they wanted to join Quantium, so it is worth having a specific answer ready before the first screen.
The behavioral stage appears in several reports. Candidates describe questions on company values, why Quantium and why the role, and how they planned and achieved a goal. One data analyst candidate described the in-person behavioral round as 45 minutes, while a graduate candidate had theirs over Zoom. Another data analyst candidate reported a lighter, conversational technical discussion covering stats, SQL and Python, and went on to receive an offer.
The harder stage is the case or live technical work. One data analyst candidate reported a live SQL exercise with three questions on a provided dataset, including segmenting sales by product type. The same candidate reported a one-hour group business problem. Other candidates described a case study where they had to explain their reasoning out loud: a graduate candidate was asked how they would determine an appropriate sample size, and an analyst candidate had 30 minutes to answer written questions, including possible reasons sales rose. Both then had to walk the interviewer through their answers. Candidates who did not get offers pointed to time pressure and explaining the why behind analytical choices.
To prepare, practice SQL aggregation and segmentation on unfamiliar tables. Rehearse structured business-case answers under a clock, and be ready to talk about working with messy data. Also learn what Quantium actually does, because one internship candidate was questioned on its current work. Evidence is mixed across data analyst, graduate and internship reports, so treat stage details as variable.

Real interview reports from people who went through the Quantium process.
My first round was a case study. I was given a written case and had 30 minutes to answer a set of specific questions about it. When time was up, the interviewer had me walk through each answer and explain the reasoning behind it, so the written work was only half of the round. The question I remember most asked for possible reasons sales had increased in the scenario, which meant proposing explanations rather than restating the numbers. The time limit was the hardest part, since 30 minutes covered several questions, and the follow-up discussion was where I had to defend my logic. I did not receive an offer. Looking back, I would spend more prep time writing structured answers under a clock and practicing how to explain them out loud.
Prep tip from this candidate
Practice writing structured answers to a business case under a 30-minute limit, then rehearse explaining your reasoning out loud, since the discussion afterward is part of the evaluation. If you get an online test instead, expect data interpretation and simple statistics with a time-management component.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report starting with an online quiz or assessment. Reports mention varied question types, numeric reasoning with tables, and data analysis or probability questions. One candidate said the final question asked why they wanted to join Quantium, so prepare a motivation answer even for this early screen.
Several candidates describe a conversation focused on company values, why Quantium, why the role, and past goals. One data analyst candidate had a 45-minute in-person session and was asked about messy data. A graduate candidate used Zoom. Format may vary by role and year, so confirm the logistics with the recruiter.
One data analyst candidate reported a live SQL round on a provided dataset with three questions, including sales segmentation by product type. Another described a straightforward technical conversation covering stats, SQL and Python. Prepare SQL fundamentals and be able to explain your queries, though not every candidate reports this round.
Case work appears in multiple reports. Candidates describe receiving a case an hour before the interview, analyzing charts and tables on paper, or answering written questions in 30 minutes. In each, interviewers asked them to walk through their reasoning, including questions such as how to determine an appropriate sample size. One candidate also reported a one-hour group business problem.
