Stripe PhD MLE Internship 90-Minute University OA

Role: PhD Machine Learning Engineering Intern
Result: Not disclosed
Timing: The exact OA day was not shared. October 2025 follows the report month.

The assessment gave 90 minutes across four sections:

1. Applied math: two questions in five minutes.
2. Statistics: three questions in ten minutes.
3. Python data and ETL: one question in 25 minutes.
4. Deep learning with PyTorch: one question in 50 minutes.

Unused time carried forward, but the candidate could not return to an earlier section.

The source preserved the format but not the seven questions. No problem statement should be reconstructed from section names alone.
