I've placed a few candidates at Anduril and have had enough candidates come back with debrief notes that I can give you a pretty reliable picture of what their recruiter phone screen looks like.
First: Anduril's talent team is solid. They're organized, move fast, and the recruiters actually know the roles. The screen is usually 30 minutes.
What gets covered: Quick resume walk. They're not reading it with you, they want to hear how you narrate your own career. What did you work on, what did it do, why did you leave. Keep it tight, 3-4 minutes. Motivation for Anduril specifically. 'Why Anduril?' is not optional, it's the first qualifying question. Vague answers about 'cutting-edge tech' don't land. Candidates who do well reference something specific: the Lattice OS, the Ghost drone, a specific defense problem they care about, or a thoughtful take on why autonomous systems matter right now. Location, clearance, and citizenship. Lots of roles are in Costa Mesa or Washington DC, some newer roles are in Seattle or Austin. Clearance eligibility (US citizenship) comes up for certain roles. The recruiter is not trying to disqualify you, they're trying to match you to the right req. Timeline and competing offers. They'll ask where else you are in the process. This is standard. Be honest, it helps them move faster if there's urgency. Comp expectations. They ask early. Know your range going in.
One thing to know: Anduril does move faster than big tech when they want a candidate. If you're aligned on the role and the mission, the loop can close in under three weeks. If you're slow to respond or vague on the mission question, they'll deprioritize and the timeline stretches.
