Candidates describe Robinhood's Data Scientist interview as a mix of technical fundamentals and product judgment, and the reports differ by stage. Two Senior Data Scientist candidates describe a recruiter screen, a combined technical and product round, and a four-round on-site: Product Analytics, Product Jam, SQL plus Python, and Experimentation. Both say the hypothetical Robinhood product case was judged on ROI and A/B testing, so tie each recommendation to measurable business impact and say how you would validate it.
SQL appears in every report. One candidate faced simple joins, another a question about user trading volume, and a third worked through window functions on two Robinhood tables in a CodeSignal section. Python in that same report meant pandas groupby and aggregation on a list of trades. Practice trade-style data and talk through partitioning, ordering and aggregation as you write.
Experiment design is the other recurring theme. A Data Scientist candidate who later accepted an offer reported an A/B test design question in the first technical round. Be ready to cover hypothesis, metrics, tradeoffs and how you would read results. One candidate who did not get an offer found the statistics question hardest, so rehearse explaining your reasoning out loud rather than reciting formulas. Outcomes vary across the reports, and the sample is small.

Real interview reports from people who went through the Robinhood process.
A former colleague recommended me for the Data Scientist position at Robinhood, which led to an initial phone screen. The technical round was pretty intense for a first step, and it centered on a SQL question about user trading volume plus an A/B test design question. The SQL part felt like the main filter, since it was clearly testing whether I could reason through a product metric cleanly rather than just write a query mechanically. The experiment question was more open-ended, but it still had a practical feel to it and seemed aimed at whether I could think through tradeoffs in a real product setting.
The structure of the questions felt familiar from standard product analytics interview prep, even though the interview itself was still challenging. I didn’t get the sense that they were trying to trick me, but they did want solid fundamentals and a clear explanation of my thinking. A few days later, I received an offer and accepted it. Overall, it was a tough but rewarding process, and I’d definitely recommend being ready for SQL on product metrics and a straightforward A/B test design discussion.
Prep tip from this candidate
Brush up on SQL questions around user trading volume and product metrics, since that was the main technical filter. Also practice explaining an A/B test design clearly and practically, because that was the other core part of the screen.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report a conversational recruiter call with baseline gatekeeping questions about background and fit. Two candidates also say they were asked to describe a project they were proud of, so prepare a concise story where data drove a decision.
Two Senior Data Scientist candidates describe a combined round with a SQL question on joins, a behavioral prompt about using data to drive a decision, and a hypothetical Robinhood product case. Interviewers reportedly wanted answers framed around ROI and validated through A/B testing.
One candidate reports a hiring manager screen mixing background questions with CodeSignal SQL and Python. The SQL used window functions across two Robinhood tables, the Python used pandas on a list of trades, and the discussion added product sense and statistics questions. That candidate did not receive an offer.
A Data Scientist candidate, referred by a former colleague, describes an initial technical round built around a SQL question on user trading volume and an open-ended A/B test design question. They report receiving an offer a few days later, which they accepted.
Two Senior Data Scientist candidates report four on-site rounds: Product Analytics, Product Jam, SQL plus Python, and Experimentation. Product Jam was described as collaborative and brainstorming-oriented, and the SQL and Python round as deeper than the earlier screen.
