Completed the Boeing final round last month for a senior software engineer role in their digital transformation group. This is the part people ask most about and I couldn't find anything recent so I'm writing it up.
Format: Four rounds, done virtually over two afternoons (two rounds each day). They didn't do a compressed single-day onsite, at least not for my loop. I've heard in-person is still available for Everett and Renton roles but most engineering roles seem virtual now.
Round breakdown: Round 1: Coding. 50 min. Two problems on a shared editor. One was graph traversal (medium), one was a database modeling question (write a schema for a maintenance tracking system). Not brutal but not easy. Round 2: System design. 50 min. Already wrote up the design question in another thread. Tl;dr: design an aircraft maintenance scheduling system. Reliability and auditability matter more than scale. Round 3: Behavioral + leadership. 45 min. Four behavioral questions, all STAR format. Safety culture framing throughout. Round 4: Technical deep dive with a senior engineer. This was a conversation about my past work: what I built, what broke, what I'd do differently. No new coding. Just talking through real systems I've worked on.
What I didn't expect: Round 4 was actually the most interesting. They really probed on failure modes and incident response. 'Walk me through a production incident you owned' came up and they dug into it for 20 minutes. SRE background helped a lot here.
The debrief wait: 8 business days. That felt long. I followed up once at day 5 and heard back on day 8. The recruiter said they had a calibration process with multiple interviewers which tracks with the panel structure.
Offer came 3 days after the verbal. Whole thing from application to offer was 7 weeks.
