Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

Behavioral

Walk me through a Python project where you had to design something from scratch instead of gluing together existing libraries.

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.

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.

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?

ability to collaborate and take feedback, since the internship is built around close mentorship

Why data engineering specifically, and why here, given you don't need a finance background for this role?

genuine motivation and whether they understand the role isn't about finance knowledge but about infrastructure craft

Technical

Say you have a Python program that needs to read from three different data sources at once without blocking. How would you approach it, and what threading or concurrency model would you use?

real understanding of threading models, not just textbook definitions

What data structure would you pick to deduplicate millions of records efficiently, and why?

depth of data structures knowledge and ability to reason about tradeoffs at scale

How do you think about ensuring data integrity when the same dataset is used by many different teams across a firm?

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?

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?

whether they use AI tools critically rather than blindly trusting generated code

If you had a database table growing by millions of rows a day and queries were slowing down, what would you look at first?

practical database management instincts under scale

Situational

Imagine a data pipeline you built starts silently dropping records overnight. How would you go about finding the cause?

debugging instincts and systematic thinking under a production-like scenario

What does a good code review look like to you, both giving and receiving one?

readiness to work inside a team practicing agile, daily-deploy development
