How it went
The interview process for a Senior Data Engineer role at Meta involved a challenging but manageable CoderPad screening with SQL and Python questions under strict time constraints. The subsequent onsite interviews were highly analytical, focusing on SQL proficiency, data modeling, and evaluating technical trade-offs. A notable round involved designing a large-scale data model and justifying scaling strategies for tables exceeding 1 TB.
