Cisco

I went through all the rounds, but at the end, they said that we will not be able to roll out the offer due to a freeze. It was very disappointing, as I had wasted my whole day in the process.

Very smooth. Hiring manager phone screening to find a match. On-site interview by four people for a total of two hours. Interviewers were cordial. Process took less than a month.

Mostly from Leetcode medium question in 3 rounds and 2 rounds of design level question and one phone screening. And networking question from past experience. L2/L3 forwarding, MAC learning, IGMP, TCP/IP, L3 routing, Tunneling.
