Applied through their careers portal in February, heard back in about 10 days. First call was a 30-min recruiter screen, pretty standard: background, clearance eligibility, salary range. Then a 45-min technical call with one engineer on the team. We talked through a systems integration project I'd led, they asked a lot about requirement traceability, verification vs. validation, and how I'd handled a scope change mid-program. Not algorithm stuff, actual systems thinking.
Then the panel. Three people, about 90 minutes total. One systems question, two behavioral rounds, then 20 mins of me asking them questions. The behavioral stuff was serious. 'Tell me about a time you had to make a decision with incomplete information and significant consequences.' Not a vibe question. They wanted specifics, numbers, outcomes.
Feedback loop was slow. Heard back with an offer about 5 weeks after the panel. The offer itself had base, bonus target, and they walked me through the pension and ESOP stuff which I hadn't expected to be as material as it was.
Overall: not a casual process. They want people who can operate in structured, regulated environments. If that sounds like you, it's worth the wait. If you're used to moving fast and breaking things, this will feel like a different planet.
