The Zip SWE interview, round by round
Recruiter screen (30 min · call)
The opening conversation. Your recruiter walks through your background, the level and team you are targeting, your timeline, and your comp expectations, and gives you a first read on how Zip works. It is rarely technical, but at a startup this stage also probes fit for a fast, high-ownership environment, so treat the culture questions as real signal.
- Anchor your level early. Targeting Software Engineer versus Senior changes the shape of the whole loop, especially how much design you will face, so be deliberate about where you position yourself.
- Show you like owning things. Zip moves fast and expects engineers to run with ambiguous problems, so have a short story ready about a time you took something end to end.
- Know your comp range. Because equity here is private-company upside, understand how you value base, options, and refreshers before the number comes up.
Technical coding screen (60 min · CoderPad)
One or two medium coding problems on a shared editor with a Zip engineer. The emphasis is practical: reach a working, reasonably optimal solution, narrate your thinking, and handle edge cases without being prompted. Communication counts as much as the final answer, since this is your first real read from an engineer on the team.
- Talk while you build. Clarify the problem, state your approach, and reason through trade-offs out loud rather than coding in silence.
- Correctness beats cleverness. A clean solution you can explain and test outperforms a fragile one-liner that misses a case.
- Expect practical framing. Problems often look like small real features rather than pure puzzles, so keep your code readable and easy to extend.
Onsite coding round (60 min · virtual)
A deeper coding interview in the onsite loop. Similar to the screen but with more room to go beyond the first solution: interviewers probe edge cases, ask you to extend the problem, and watch how you keep code clean under follow-up pressure. Core data structures and algorithms carry this round.
- Optimal and defended. Land a solution with reasonable time and space, then defend the complexity and the trade-offs when they push.
- Extend without rewriting. Expect a follow-up that changes the requirements, so structure your first pass so it bends instead of breaking.
- Recurring themes. Hash maps, trees, graphs and BFS/DFS, sliding window, heaps, and interval problems show up most.
System design round (60 min · virtual)
The design interview, framed around problems close to what Zip builds: approval flows, configurable workflows, and integrations across the systems a procurement platform touches. You design a real service end to end, covering the API, data model, how state moves through an approval chain, and how integrations stay correct under failure. Depth on trade-offs matters more than naming technologies.
- Model the workflow. Approvals, routing rules, and state transitions are the heart of the problem, so get the data model and state machine right before optimizing anything.
- Design integrations for failure. Third-party and ERP-style integrations fail and retry, so plan for idempotency, retries, and consistency, not just the happy path.
- Scope out loud. Ask what matters most, size the problem, and defend where you spend depth; a clear scope beats an over-engineered diagram.
Behavioral & hiring-manager round (45 to 60 min · virtual)
A conversation with the hiring manager and often another leader on how you work, not just what you can build. Expect questions on ownership, ambiguity, collaboration, and how you make decisions with incomplete information, plus a two-way discussion of the team and its roadmap. At a startup this round weighs heavily, since a small team is betting on how you operate day to day.
- Bring specific ownership stories. One or two concrete examples of driving something end to end, with your exact role and the outcome, land better than general answers.
- Be honest about ambiguity. Interviewers want to see how you move when the problem is underspecified, which is most of the time at a fast-growing company.
- Ask real questions. The hiring manager is also selling you, so thoughtful questions about the team and roadmap are part of the signal.

How to prepare
Keep a daily coding rhythm (Weeks 1 to 4)
Code every day. Rotate through the patterns a modern B2B-SaaS loop leans on, hash maps, trees, graphs and BFS/DFS, sliding window, heaps, and intervals, mostly at medium difficulty, always timed on a shared editor with your reasoning spoken out loud.
Practice practical, extendable code (Weeks 1 to 3)
Zip's problems often look like small real features, so drill writing clean, readable solutions you can extend when the requirements change mid-interview. Practice narrating trade-offs and handling follow-ups without rewriting from scratch.
Layer in workflow-style system design (Weeks 2 to 3)
Once your coding is warm, work through a few full designs centered on approvals, configurable workflows, and integrations: API, data model, the approval state machine, idempotent retries, and failure handling. Say each decision aloud and prepare for trade-off follow-ups.
Prepare ownership and ambiguity stories (Weeks 2 to 4)
Draft a handful of specific stories about taking something end to end, working through ambiguity, and collaborating under time pressure, each with your exact role and the outcome. Rehearse delivering each in about two minutes for the behavioral and hiring-manager round.

About Zip
Zip builds procurement orchestration software for enterprises, an intake-to-pay platform that gives any employee a single front door to start a purchase request and then routes it through the approvals, workflows, and integrations a large company needs before money is spent. It sits across finance, legal, IT, and security systems, which makes the engineering problems heavy on configurable workflows, correctness across integrations, and state that has to stay consistent as a request moves through many hands.
Founded in 2020 by two former Airbnb employees, Zip is a venture-backed private startup headquartered in San Francisco. It has grown quickly by defining the intake and orchestration category for procurement, and engineering hires span the workflow engine, integrations, and the platform that ties them together. Expect a fast, ownership-heavy environment where engineers are trusted to run with ambiguous problems.
Frequently asked
What does Zip build?
Zip is a procurement orchestration platform, sometimes called intake-to-pay. It gives employees one place to request a purchase and then routes each request through the approvals, workflows, and integrations an enterprise needs, connecting finance, legal, IT, and security along the way.
How many rounds is the Zip interview?
Typically around five stages: a recruiter screen, a technical coding screen, and an onsite that covers a coding round, a system-design round, and a behavioral or hiring-manager conversation. The exact shape varies by team and level.
How hard is the Zip SWE interview?
Medium and practical. Most coding sits at the medium level and often looks like small real features rather than pure puzzles. The harder signal comes from the system-design round and from showing genuine ownership, not from exotic algorithms.
Does Zip ask system design?
Yes, from the mid-level up. Design rounds tend to center on the problems Zip actually solves: approval flows, configurable workflows, and integrations, where modeling state correctly and handling failure matter more than naming technologies.
What coding topics does Zip focus on?
Core data structures and algorithms: hash maps, trees, graphs and BFS/DFS, sliding window, heaps, and interval problems. Most questions are LeetCode-medium in spirit, with an emphasis on clean, readable, extendable code.
Is the Zip interview a LeetCode grind?
Less than at some big-tech loops. The coding is real but practical, and interviewers care a lot about how you communicate, handle follow-ups, and keep code maintainable. Pattern practice still helps, but product sense and clarity matter alongside it.
What is the system-design round like at Zip?
You design a real service end to end, usually framed around approvals or workflows: the API, the data model, the approval state machine, how integrations stay correct under retries and failure, and where you would scale. Depth on trade-offs beats a broad diagram.
How is compensation structured at Zip?
As a private startup, Zip pays a competitive base plus equity, typically stock options or RSUs. That equity is real ownership but illiquid until a liquidity event, so its eventual value depends on the company's outcome rather than a public share price.
Is Zip equity worth anything before an IPO?
Private-company equity has real potential upside but no guaranteed value and no easy way to sell before a liquidity event. Weigh it as long-term upside on top of your base and any sign-on, and understand the vesting and strike terms before you sign.
What is the pace like at Zip?
Fast and ownership-heavy. As a fast-growing startup, Zip expects engineers to run with ambiguous problems, ship, and take responsibility end to end. The interview probes for this directly, so bring stories that show you thrive without heavy process.
How long does the Zip interview process take?
Usually about three to four weeks from recruiter screen to onsite, then a short window for the decision. A leaner startup loop can move faster than a big-company process when schedules line up.
Does Zip hire remotely?
Zip is remote-friendly and hires across US locations alongside its San Francisco base and other hubs, though specific roles may prefer a hub or in-office presence. Confirm the arrangement for your target team with your recruiter.
Where is Zip located?
Zip is headquartered in San Francisco, California, with additional presence in other US and international hubs and a remote-friendly stance for many engineering roles.
How should I prepare for the Zip interview?
Keep a daily medium-level coding rhythm with clear communication, practice clean and extendable code that survives follow-ups, work through a few approval- and workflow-style system designs, and prepare specific ownership and ambiguity stories for the behavioral round. Karavine's Zip pack is exactly this plan with worked solutions.
What does the behavioral round at Zip look for?
How you operate: ownership, decision-making under ambiguity, and collaboration on a small, fast team. The hiring manager often runs it and is also selling you the role, so bring concrete stories with your exact contribution and come with real questions about the team.
What levels does Zip hire engineers at?
A typical startup ladder runs from Software Engineer through Senior, Staff, and Principal. Higher levels shift the loop toward system design, architecture judgement, and cross-team scope, and away from pure coding.
