Our candidates report that UnitedHealth Group tends to value hands-on engineering judgment more than polished theory. The live SQL work is practical and often layered, with prompts that force you to reason through windowing, ordering, and business logic in one pass. One candidate specifically called out an advanced query about finding top orders dispatched to a user where the order amount exceeded the previous order, which is a good signal that they want to see how you think through real data patterns, not just syntax.
A recurring theme is that the conversation quickly moves from queries into the systems behind them. We’ve seen interviewers ask about the database tools you’ve used, the kinds of processing you’ve built, and the principles you follow when designing pipelines. That tells us they care about whether you can explain why a pipeline is structured a certain way and how you make tradeoffs around reliability and efficiency. Cloud knowledge also comes up in a concrete way, especially around AWS services that would fit an efficient pipeline.
The other non-obvious piece is that this is not treated as a purely technical screen. Our candidates report that team and culture fit is part of the evaluation, so the strongest responses connect engineering choices to collaboration and clarity. In practice, that means the people who do best are the ones who can defend their design decisions while sounding like someone others would want to work with on a production data stack.

Synthesized from candidate reports. Individual experiences may vary.
The interview consisted of three online rounds focused on practical data engineering skills. Candidates were asked to solve live Python and SQL problems, including advanced SQL queries such as identifying top orders dispatched to a user where the order amount was greater than the previous order.
Interviewers also asked about the database management tools used, prior data processing experience, and the core principles followed when building data pipelines. There was additional cloud discussion around which AWS services would be useful for an efficient data engineering pipeline.
The loop included evaluation of team and culture fit, so candidates needed to explain both their engineering decisions and how they collaborate with others. This stage was conversational but still tied to the technical work and the way the candidate approaches teamwork.
