Cisco Interview Experience

There are three rounds of interview :

Technical interview:  First, they asked me to tell about myself, then they asked me to find the maximum element in an array in python as I mentioned I was good at coding in Python. As Cisco company is based on networks they asked me about OSI layers in it and briefly explain each layer. Then the interviewer asked me which layer I am comfortable with, I answered them with the last four layers so the Interviewer asked 3-5 questions on each layer

Managerial round: First, the interviewer told me to take some time and drink water before the interview starts. In this round, the questions were based on my resume. So I would suggest everyone prepare their resume thoroughly about the skills and project you mentioned. As there was a little more time so Interviewer asked me what will be written on a coin or note and why the year is mentioned on the coin?

HR round: The interviewer asked me to tell him about myself and then he asked about my hobbies. Next, he asked me whether I am ok with the timings and to sort the order of place of work
