Meta Network Production Engineer · intern prep
Coding interview first (45 min, CoderPad, Python), then a network technical interview · one topic at a time, LeetCode tracker in parallel
About two weeks of prep. The day plan runs to the coding screen; after that, work the network topics in order. LeetCode is not topic-by-topic: the tracker serves one mixed queue of problems, so just keep solving the next one. If time runs short, finish the coding topics (odd numbers) and topics 6, 8, 14, 19 first.
The official guide grades file handling, data structures, Big-O, common algorithms, plus structure, syntax fluency, bugs, correctness and efficiency. Candidate reports add a network round built around TCP/IP, ARP/DHCP/DNS, subnetting, L2, OSPF/IS-IS, BGP in depth and troubleshooting scenarios. Topics alternate Code and Network.
