Rippling Front End Interview Questions
Find the latest version of this page on GreatFrontEnd's Rippling Front End Interview Guide.
Rippling's "front end" loop is functionally a full-stack loop. Expect a UI/React coding screen, a web-API design round, a LeetCode-style algorithm round, and a system design round. Be ready to spin up a small Node/Express server during the API round.
JavaScript coding questions
- Implement
Event Emitter.- Practice question (Free)
- Implement a hand-rolled
throttle(no library imports allowed in the screen).- Practice question (Free)
- Dedupe a list of fetched items by ID using a
Setof seen IDs. - Implement
flattenon a nested array.- Practice question (Free)
- Implement
Function.prototype.bind.- Practice question (Paid)
User interface coding questions
- Build a job board: fetch and display posts, add a "load more" button, then layer on infinite scroll using
IntersectionObserver, throttling on scroll, and deduping of fetched items.- Practice question (Free)
- Forms and data transformations with React. Practice controlled inputs, validation, and manipulating arrays of records.
System design questions
- Design Shutterstock (image marketplace).
- Web-API round: bring a basic HTTP server (Node/Express or equivalent) and implement CRUD endpoints for a service such as notifications, then discuss broader systems engineering / security / monitoring concerns.
Algorithm
LeetCode-tagged questions for Rippling appear in their LC company list. The most commonly reported one is Commit/Rollback key-value store.

The Rippling phone screen problem ramps quickly. The full progression is:
- Set up state.
- Fetch API with error handling.
- "Load more" button UI + pagination (you wouldn't know about this unless they tell you).
- Infinite scroll + throttle + dedupe (no library imports allowed).
I got 1–3 done and partial 4 — and got rejected. Honestly this is too much for a 1-hour screen. You need butter-level fluency to finish it cleanly. Practice IntersectionObserver, a hand-rolled throttle, and deduping with a
Setof seen IDs.

Got asked the IntersectionObserver question for the tech screen. Got data fetching working, displayed it, added a "load more" button, but stumbled on the IO implementation. I knew about it but had never had to use it raw — at work we use wrappers / common components. Worth practicing it from scratch before this screen.

Heads up: Rippling's "frontend" position is fully evaluated as full-stack. Don't be surprised when the rounds include backend / web-API work. They'll ask you to bring a simple Express (or any) Node server and implement CRUD APIs for something like a notification service, then do Q&A on broad systems engineering, security and monitoring.
29th Nov 2024:
There's a small subset of LeetCode questions tagged for Rippling. The most commonly reported one is the Commit/Rollback key-value store.

I passed the Rippling loop back in May. Inside the Marketing org so the loop might've been on the lighter side:
- System design round: build Shutterstock.
- Chat with the VP.
- Standard LeetCode-style coding round.
