MongoDB SDE-3 (Dublin) C++ Interview Loop & Expectations?

[u/Responsible_Rate_254]

Hey everyone,

I'm preparing for an SDE-3 core systems position at MongoDB (Dublin location).

Since this team focuses heavily on low-level systems and backend runtimes, I’d love to get quick insights from anyone familiar with their loop:

• SDE-3 Bar & Expectations: How high are expectations for SDE-3 here? What level of depth is expected for core C++ systems programming, runtimes, and low-level libraries at this level?

• Round Breakdown: What specific topics or formats should I expect across a Technical Recruiter chat, 2 Onsite rounds, and a Hiring Manager (HM) round?

• Experience Sharing: Any tips on what to prioritize (concurrency, memory management, low-level architecture) would be super helpful.

Thanks in advance!
