I received a call back in early February and completed the Online Assessment (OA), which was fairly easy.

I moved on to the Coding Onsite Interview round the following week.

Since Meta was close to their hiring cutoff period, what normally takes three months was to be wrapped up in under a month.

The coding round went well, followed by the Networking interview. For some reason, the interviewer wasn't available, so the interview had to be pushed back by three weeks.

I gave the final round in the first week of March and received a rejection a few days later.

Networking was solely focused on Layer 2.

TCP/IP, OSPF, DHCP, and a few other protocols were discussed.

The opening question was, "What is your favorite L2-L3 protocol?" Then, the questions slowly built around this, and negative scenarios were thrown in as well.
