Anduril Interview Questions
& Process for Software Engineers

Anduril runs several near-different software loops under one careers page, and the fastest way to waste a month is to prepare for the wrong team. Autonomy in C++ and Rust is almost a different interview from the Lattice platform and full-stack world, so confirm your team at the first recruiter contact. The spine holds across candidate reports: an application, a recruiter screen that routes your team and checks ITAR eligibility, a coding phone screen, and an onsite with the team where the offer is decided. Anduril lists its open engineering roles on its own careers site.

The center of gravity is not where a big-tech plan expects. Anduril is a defense-tech company with a broad, team-split software org built on the Lattice platform, and mission fit is read in every room. The coding is a standard LeetCode medium bar rather than a marathon take-home, but the distinctive gate is the system design round, which models a mission-critical component rather than a web-scale service. The bar is genuine and decisions are fast but sometimes opaque.

Past the screens the loop turns onto the team you would join. The coding phone screen comes first, in a shared editor and a team-dependent language, pitched as a standard LeetCode medium with a prompt that is often vague on purpose. Then comes the onsite, where Anduril's real signal lives: two coding rounds, a mission-critical system design, and a behavioral read on why you want to build defense technology.

The interviews to plan around are those onsite conversations, because that is where the holistic decision is really made. Interviewers press on depth: idiomatic and readable code, a clean design for a small system, and fundamentals probed until they reach the edge of what you actually understand. Mission fit is weighted alongside correctness, which is why the loop rewards genuine motivation, taking a hint well, and saying plainly when you are unsure.

The Phone ScreenCoding

A collaborative coding round in a shared editor. The language is team-dependent: some screens are told to be in C++, others accept Python. Style skews standard LeetCode at a medium ceiling, and the prompt is often vague on purpose so you clarify before writing code.

The OnsiteThe bar

Commonly two coding rounds, one system design, and one behavioral, with the round count and mix varying by team and level. This is where the genuine bar lives and where mission fit is read.

The System Design RoundDistinctive

A distinctive round: not web-scale distributed systems, but the design of a component of a centralized, mission-critical system, such as a UAV feature, a radar system, or an autonomy pipeline. Standard Alex Xu prep misfits it.

Anduril's coding surface is standard LeetCode at a medium ceiling, frequently skinned in the defense domain. The signature example is a border-sensor problem that is really binary search on the answer, and other rounds lean on a monotonic stack, grid BFS, and robustness-heavy expression evaluation. There is no strong evidence of a signature take-home gate, so treat live coding as the norm.

The differentiator is the style, not exotic problems. The prompt is often vague on purpose so you clarify before writing code, then escalates through edge cases and added constraints, and producing working code through each phase matters more than a perfectly optimal solution. The language is team-dependent: C++ for embedded and autonomy screens, Python accepted on others.

Get the honest version first: Anduril does not run a generic hyperscale-web design round. A recruiter reportedly told a candidate it is not a distributed-systems interview but the design of a component of a centralized, mission-critical system, so standard Alex Xu prep misfits it.

What takes its place is a domain modeling problem: design a mission-critical component such as a radar or sensor-fusion feature, a UAV capability, or a piece of an autonomy pipeline. The register is engineering done well for a real-time, safety-critical setting, the right components and responsibilities, sensible interfaces, and the failure handling that keeps the system trustworthy.

So read the round as component and domain design, not distributed scaling for its own sake. Prepare one mission-critical component end to end, from requirements to components to the key data paths, and be ready to justify each choice and extend the design when the interviewer adds a requirement mid-round.

An Anduril offer is base plus equity plus a small cash bonus, and the equity carries the upside. The catch is that Anduril is still private, so that equity is granted as RSUs you cannot sell until or unless the company goes public, which is the core thing candidates weigh at offer time. The vest is a standard four-year schedule with a one-year cliff. Hiring is also gated by ITAR, so most roles require US-person status. The exact figures live in the offer lesson rather than here.

Comparison sites map Anduril onto an IC ladder from IC2 to IC7; read that as an outside normalization, not Anduril's own internal codes. The compensation for each level lives in the offer lesson.

The shape is the durable part. Base carries the offer at every level but never runs away from it, the RSU grant grows as a share of total comp as you climb, and the cash bonus stays small throughout. Read any headline total as an approximate figure on a thin, self-reported sample that drifts as new offers land.

With the bonus small and an ITAR gate on eligibility, the movable surface is base, the RSU grant, and level. Level sets the band for that grant, so the level you enter at is the largest lever on your total, and a competing offer is the strongest reference point. Reports caution that there may not be a lot of room for new hires, so anchor carefully.
