Glassdoor Data Scientist Interview Guide

Our candidates report that Glassdoor is looking for data scientists who can move comfortably between clean SQL, product thinking, and clear explanation. The standout signal here is not raw difficulty so much as structured reasoning under practical constraints: one candidate described straightforward SQL that still demanded precision, alongside a product case with A/B testing where the real test was how well they could articulate experiment design and tradeoffs. That combination tells us Glassdoor cares about people who can connect analysis to decisions, not just produce an answer.

A recurring theme is the tone of the interviews themselves. Multiple candidates noted that interviewers were kind, professional, and conversational, which usually means the company is paying close attention to how you collaborate and communicate when the problem gets ambiguous. We’ve seen that the behavioral portion is less about rehearsed stories and more about whether you can explain your thinking naturally and credibly. In other words, clarity of reasoning matters as much as correctness.

The questions shared also point to a fairly standard but revealing bar: binary tree validation and SQL-style prompts show they still expect solid fundamentals, while the experiment and survey questions suggest a product analytics mindset. The non-obvious make-or-break factor is whether you can keep your answers grounded in the business context of a marketplace like Glassdoor — where measurement, user trust, and product tradeoffs are tightly linked.
