Anduril's engineering process starts with a recruiter screen and a technical screen, followed by an onsite loop with coding, design, and behavioral interviews. Interviewers assess how quickly you implement, how well you understand the systems you design, whether you take ownership of your work, and how clearly you explain your interest in defense technology.

What to Expect: Anduril Interview Process

Anduril's current process description lists a recruiter screen, a collaborative technical phone interview, and four onsite interviews. The onsite loop typically includes two coding interviews, one system design or object-modeling interview, and one behavioral interview. For embedded, autonomy, perception, and infrastructure roles, expect additional discussion of the team's technical domain.

During coding rounds, interviewers look for clean decomposition and clear communication. Design discussions may cover both distributed software and concrete domain constraints. Behavioral questions focus on past projects, speed in ambiguous situations, motivation for the work, and judgment about the product.

Learn enough about the target team's product to ask specific questions about deployment, operators, and constraints.

How to Prepare and Pass Anduril Interviews

Give yourself six to eight weeks. Review algorithms, graphs, dynamic programming, object design, distributed-systems trade-offs, and C++ basics if the role requires them. Practice writing code in 45 to 60 minutes while explaining your assumptions and tests.

Prepare three project stories that cover architecture, failure modes, and your individual contribution. Use Lodely to combine company-specific coding, system design, and behavioral prompts at a difficulty similar to the interview loop.

Anduril Interview Breakdown

Tell Me About Your Past Projects

Type: Project deep dive.

The Trick: Choose two or three related projects and explain the decisions you made, your individual contribution, and the results.

What It Tests: Scope, ownership, and technical depth.

Max Profit from Cutting Rods

rods = [10], salePrice = 5, costPerCut = 2, saleLength = 3

41

rods = [5,5], salePrice = 10, costPerCut = 1, saleLength = 5

100

Type: Greedy optimization.

The Trick: Calculate profit by the number of cuts and skip any rod with a negative contribution.

What It Tests: Modeling, integer arithmetic, and edge-case handling.

Team Arrangement

Type: Constraint-based algorithm.

The Trick: State the invariant before choosing a data structure, then prove that every ordering preserves it.

What It Tests: Translating rules into an ordering or search strategy.

Three additional algorithmic prompts, Digit Encoder, Surveillance Footage, and Border Security, cover direct implementation, search, and optimization. "How do you hire your team?" tests leadership judgment, evidence, calibration, and fairness.

What Comes After The Interview

If you receive an offer, review base salary and annualized equity separately. Anduril packages include salary and RSUs, and equity varies by level.

Candidate Experiences

One recent software candidate described a collaborative technical screen followed by two onsite coding interviews, a system design interview, and a behavioral discussion. One coding prompt was much harder than the recruiter had described, and the interviewer offered no hints. Continue explaining your reasoning and checking your approach even when the interviewer gives little feedback.

Conclusion

Anduril evaluates executable code, grounded design, deep project ownership, and clear motivation for its defense mission. Practice these seven company-specific examples on Lodely before the onsite loop.
