Take-home / Online Assessment
A practical coding challenge in your own IDE — not a LeetCode sandbox. Rippling grades this like a PR review: does the code actually run, are edge cases covered, and does the README explain your reasoning rather than just describe the code? The problem domain is always anchored in Rippling's product — payroll calculations, benefits enrollment, or employee event processing.
What to expect
- e.g., 'Parse a stream of employee events (hire, salary-change, terminate) and compute net pay for each employee in a given pay period, with pluggable deduction types' — the classic version of this problem
- e.g., 'Build a benefits enrollment eligibility checker: given a plan's rules and an employee's attributes (start date, employment type, hours), return eligible plans and total cost'
- The edge case that kills most take-homes: an employee hired and terminated within the same pay period — most candidates either double-count or skip them entirely
- A README that says 'I chose this schema because…' beats one that says 'This code parses employees' — interviewers want reasoning, not narration
- Missing tests on boundary inputs (zero deductions, mid-month hire, overlapping plans) is the fastest way to get screened out at this stage

Coding Round 1
One to two medium algorithmic problems, typically graph or tree problems with a workforce-management framing. Rippling interviewers want working code — this is run in your own environment, not on a whiteboard. Narrating the brute force past the 10-minute mark without self-correcting signals a red flag faster than a wrong answer.
What to expect
- e.g., 'Given an employee permission inheritance tree (roles inherit permissions from parent roles), determine the effective permission set for a user at any node' — DFS with accumulator, memoize for repeat queries
- e.g., 'Find the minimum set of policy groups that ensures all employee roles satisfy compliance requirements' — set cover greedy approximation on a bipartite graph
- Your code must compile and run — Rippling interviewers are explicitly critical about untested, non-running code
- The follow-up is almost always a scale constraint: 'This runs on every API request for 50K companies — how do you cache it?'

About Rippling SDE-1 Interviews
Rippling SDE-1 interviews test practical engineering judgment, not just algorithm recall. The process includes a take-home coding challenge graded on execution quality and a README explaining your trade-offs, followed by algorithmic rounds anchored in HR, IT, and payroll domain problems — permission inheritance trees, org-chart traversal, and employee data aggregation. Rippling's compound-software model means every engineer ships end-to-end product features across HR, IT, and Finance, and the interview is designed to surface that capability.
