Rippling Interview Question Bank

Rippling's engineering loop is unusually concentrated: a small set of OOD coding prompts, two data-heavy system-design prompts, and a practical web API round account for most SWE interviews. The bar is driven by speed through multi-part prompts, clean extensible design, and whether the candidate can collaborate with AI tools without losing ownership of the solution.
