Anduril Senior Software Engineer interview questions

2 phone rounds, onsite consisted of 4 rounds. 2 coding and 1 sys design and 1 behavioral. Company is notorious for not reimbursing the expenses for onsite. Keep that in mind before interviewing. HR ghosted me when confronted.

First round was a debug this broken code problem (virtual). The full loop consisted of the typical system design, 2x coding, and behavior portions (all virtual with the option to split over 2 days). I "passed" the full loop (final round), but the team thought I would match better elsewhere, so the recruiter pinged some chat to see if any other teams were interested. He got 2 replies which meant two more interviews. My first follow-on was another round of coding and behavioral interviews, but in person this time. I also "passed" this round, but the team decided not to move forward with hiring for whatever reason. The recruiter was even confused why they decided to not hire me. The second team matching phase was a call with a manager, but he was looking for a specific skillset. All in all, after multiple "passes" and sunk hours, I never received an offer. Seems like they're still figuring out how to do interviews over there.
