Basic CCNA level questions. Questions on Optics and Layer 2 packet flow. Scenario based questions, network designing. Couldnt get the offer due to lack of knowledge in physical connection of devices and fiber optics.

There's 3 rounds in total. 2 rounds online and final round in person. First round was with the recruiter. It was around 30 mins, and it was all about behavioral stuff. The second round was with an engineer. I was asked about OSI, STP, subnetting, and other core networking stuff. Final round was in person at Philadelphia. It consisted of 2 rounds. It was all scenario based questions starting from network design, L1, L2, and everything. They asked a lot about redundancy, vlans, switching, routing, and subnetting.
