Expense Rules & Balances

The expense rules question is the second most-described Rippling coding question. Rippling sells corporate cards, and managers set the spending rules on them, so the question puts you on that product, with rules that arrive as data instead of code.

The rejection reason candidates quote most is hardcoded rule values. Write each rule as an object built from its config, behind one shared method, and every follow-up then costs one new class. A later part checks rules across groups of expenses.

The balances problem comes last. It needs the same exact cents, and it starts by netting everything before any matching.
