From my experience, the Meta software engineer interview process started with a recruiter call where they walked me through the structure and expectations. After that, I had a couple of technical phone screens, each about 45 minutes, focused on solving algorithmic and data structure problems in a shared editor. The questions were straightforward but designed to test not just coding ability, but also how well I could explain my reasoning, optimize solutions, and think through tradeoffs under time pressure. The onsite loop (in my case, done virtually) consisted of multiple coding rounds, a system design interview, and a behavioral interview. The coding sessions were a bit more challenging than the phone screens, but still followed the same style. The design interview pushed me to reason about scalability and architecture, while the behavioral portion centered around Meta’s values and how I approach problem-solving and teamwork. Overall, the process was rigorous but fair, with a clear emphasis on structured thinking, coding fluency, and communication.
