Meta Network Engineer Intern interview questions

First-round is 20 multiple choices in 18 minutes about TCP/IP, Linux command, and python, if you pass the first round, then the second round is a coding interview, the last round is a network interview.

After the resume screening, I received a link for an online assessment (MCQs on Python code snippets, Linux network troubleshooting commands, Networking basics). The second round was a whiteboard coding interview with an engineer from Meta with 2 LC med questions. The interviewer was very kind and helped navigate in the right way. The final round was Networking basics interview - TCP (flow control, congestion control, sliding window, handshake process), IP (fragmentation, subnetting), BGP (Packet types, attributes, best path selection), OSPF, ARP, linux network troubleshooting (ping, trace route, netstat etc.), how packet flows from one source to another (in detail)
