Stripe US Internship Card-String Team Screen

Role: Software Engineering Intern in the United States
Result: Advanced to the onsite; final result not disclosed
Timing: The exact screen day was not shared. October 2024 follows the report month.

The screen used three card-string tasks:

1. Parse card values that begin with a two-digit length.
2. Keep only cards supported by the system.
3. Expand generic prefixes into an ordered list without duplicates.

One confirmed example moved a later exact card behind the cards created by an earlier generic prefix. A different broad-prefix behavior was only the candidate's guess and was not confirmed.

The candidate passed the simple examples for Part 3 with little time left. A later update named invoice coding and Bikemap Route and JSON Integration in the onsite, without more detail.
