Our candidates report that Sezzle tends to screen for more than technical fluency; it wants to see whether you can think like someone building in BNPL. Even in the earliest assessment, the signals leaned toward fintech vocabulary, product intuition, and metric awareness rather than narrow theory. That matters because the company sits at the intersection of e-commerce and credit risk, so candidates who can connect modeling choices to customer behavior and business outcomes seem to stand out.
A recurring theme is that Sezzle appears comfortable probing the fundamentals, but in a very applied way. The questions we saw around regularization, validation, bias-variance tradeoff, and class imbalance in finance suggest they care about whether you understand how models behave under real-world constraints, especially where false positives and false negatives have business consequences. We’ve seen this pattern before in lending-adjacent interviews: the strongest candidates don’t just define the concepts, they explain why a given tradeoff matters for approval rates, risk exposure, or downstream conversion.
Another non-obvious signal is the format itself. The recorded assessment with cognitive, personality, and motivation sections suggests Sezzle is also evaluating how you communicate under low-friction, high-autonomy conditions. In our view, that means the bar is less about polished performance and more about whether your reasoning feels grounded, structured, and credible for a product-facing data scientist.

Real interview reports from people who went through the Sezzle process.
I was in the assessment stage for Sezzle, and I had not done a phone screen or anything yet. The only instruction I got was that it was a one hour assessment with cognitive, personality, and motivation sections, and I had to record a video and upload it. I had been out of interviewing for more than five years, so I was pretty rusty, and I had applied to more than 50 jobs before I got this one or two calls. Before the mock, we talked through what Sezzle is, the BNPL space, and how the interview would probably lean on fintech terminology, product sense, metrics, SQL, Python, and maybe some probability or stats. The coach said the process could be just one phone screen and one or two interviews, or it could turn into a full loop with SQL, Python coding, and EDA, but for my actual Sezzle process I was still only at the assessment stage.
Prep tip from this candidate
For Sezzle, be ready to speak in BNPL and fintech terms, not generic product language. The coach kept stressing that the product sense answer should start with strategy, North Star and guardrail metrics, then move into execution and feature ideas tied to the payment structure.

Synthesized from candidate reports. Individual experiences may vary.
Candidates may be asked to complete an initial assessment before any live interview. In the reported experience, this was a one-hour assessment with cognitive, personality, and motivation sections, and required recording a video and uploading it.
Based on the reported guidance, some candidates may have a single phone screen after the assessment. This stage likely covers background, motivation, and high-level fit for Sezzle and the BNPL/fintech space, with some discussion of product sense and role expectations.
Depending on the candidate, the process may expand into one or two additional interviews. These can include SQL, Python coding, EDA, metrics, and probability/statistics, with an emphasis on fintech terminology and practical data science problem solving.
