Stripe Internship Min-by-Key and Ordered-Columns Screen

Role: Software Engineering Intern
Result: Not disclosed
Timing: November 12, 2019

The screen used two row-selection tasks.

1. Return a row with the minimum value for one key. Missing columns counted as zero, and any tied row was acceptable.
2. Compare rows using an ordered list of columns, moving to the next column when values tied.

The report did not preserve bounds, empty-input behavior, or the final return shape.

The candidate prepared with Java and unit tests and explained the approach while coding. The earlier OA task was not shared.

Practice: Toy Database — Select a Row by Ordered Keys.
