Walk me through a Python project where you had to design something from scratch instead of gluing together existing libraries.
What they are checking: whether they can build real solutions rather than just wiring up packages, matching the posting's emphasis on solving problems from scratch
Tell me about a time you had to learn a new part of a codebase quickly to fix or extend it.
What they are checking: adaptability and ramp-up speed, since interns must contribute to production code fast
Tell me about a time you shipped something imperfect because the deadline mattered more than polish.
What they are checking: fit with a fast-paced, deploy-daily environment and comfort with iteration over perfection
Tell me about a time you disagreed with a teammate or mentor about how to implement something. What happened?

What data structure would you pick to deduplicate millions of records efficiently, and why?
What they are checking: depth of data structures knowledge and ability to reason about tradeoffs at scale

What they are checking: awareness of downstream consequences and firm-wide data quality thinking
Describe your experience running Python on Linux. What kind of environment issues have you had to debug there?
What they are checking: hands-on comfort with the actual platform they'll work on, not just familiarity in theory
How have you used AI coding tools like Claude Code in your own projects, and where did you have to double check or override what it gave you?
