Lattice is the leading performance management and people analytics platform — used by 5000+ companies for reviews, goals, 1:1s, and engagement surveys. The interview is enterprise-SaaS-flavored with focus on workflow design, complex data modeling, and the realities of building tools used by HR teams.
Process
Recruiter screen → 60-minute coding phone (DSA medium) → onsite virtual: 2 coding, 1 system design, 1 craft deep-dive, 1 behavioral. Cycle: 3–4 weeks.
What they actually ask
- Design a 360-review system with manager, peer, and direct-report inputs. Model the cycle as a state machine (draft → submitted → shared → closed) and think through how one review request fans out to several reviewer types without leaking who wrote what. Interviewers probe how you handle declined or late reviewers and how a manager’s summary rolls up anonymous peer comments.
- Design goal-tracking with cascading from company → team → individual. Treat this as a tree where parent goals aggregate progress from their children, so be ready to recompute a rollup when one leaf changes without recalculating the whole tree. Expect follow-ups on re-parenting a goal mid-quarter and on weighting each child’s contribution.
- Design engagement-survey aggregation that preserves anonymity. The tension is exposing useful team-level breakdowns while never revealing a single person’s answer. Propose a minimum-response threshold (for example, hide any segment with fewer than five responses) and be ready to explain how stacked filters could otherwise re-identify someone.
- Coding: medium DSA, often with workflow or graph flavor. Practice traversals, dependency ordering, and state-machine problems over heavy dynamic programming, since the graph questions map straight onto org charts and approval chains. Clean code and edge-case handling count for more here than exotic algorithms.
- Behavioral: customer focus, navigating HR domain complexity. Bring stories about shipping for non-technical users like HR admins and making a judgment call when the requirements were ambiguous or sensitive. Keep each answer in STAR shape and be specific about the trade-off you chose.

Prep priorities
- Be fluent in TypeScript/React for frontend; Ruby on Rails for backend. Interviewers let you pick a language but expect idiomatic code, so know your framework’s data-fetching and state patterns cold instead of fighting syntax. Matching Lattice’s own stack (React on the front end, Rails on the back) helps in the craft deep-dive.
- Understand survey design and anonymity-preserving aggregation. Be ready to reason about response thresholds and why you cannot show a chart for a team of three. This idea surfaces in both the system design round and the product-sense discussion.
- Brush up on workflow engines and approval-graph patterns. Review how state machines and directed graphs model review cycles and approval chains; the review, goal, and survey products are all workflow engines underneath.
Frequently Asked Questions
Is Lattice remote-friendly?
Hybrid in San Francisco, NYC, London, and others. Many engineering roles fully remote within supported countries.
How does Lattice compare to Culture Amp or 15Five?
Lattice has the broadest product (reviews, goals, 1:1s, engagement). Culture Amp leads on engagement; 15Five on continuous performance. Comp is comparable.
What is the engineering culture?
Mid-stage SaaS — collaborative, customer-driven, healthy work-life balance. Strong product-engineering partnership.
