Anduril Industries

LeetCode-medium problems wrapped in defense stories — drones, sensors, border towers — with deliberately vague prompts that grow in phases. Clarifying constraints and extending working code is what gets graded; senior screens add “what if the input were massive?”

Typical loop

  1. 1Recruiter screen: 30 min — why Anduril, comfort with defense work
  2. 2Technical phone screen: 60 min on HackerRank CodePair — one multi-phase medium (~10 min intro, ~40 coding, ~10 for your questions)
  3. 3Some teams add a hiring-manager call: resume plus role-specific coding
  4. 4Final loop, ~4 × 60 min: two coding rounds in the same multi-phase style
  5. 5System design / OOD round (radar-tower model, data-structure design)
  6. 6Behavioral with senior staff: line-by-line resume drill
