Stripe Internship Platform-Balance OA

Role: Software Engineering Intern
Result: Rejected the next day
Timing: OA on October 12 and rejection on October 13, 2018.

The task used optional destination-account and amount fields in a platform-balance flow.

The candidate believed that a missing merchant might use zero, an account-only destination might send all money to that merchant, and an amount-only destination might deduct that amount. These were hidden-test diagnoses, not confirmed rules.

They passed tests 5 and 12 but failed test 8. The complete allocation, parsing, and output contract was not preserved.

Practice: Compute Platform Balance Destinations.
