Cisco Software Developer interview questions

I spoke with a very kind recruiter for my initial phone screen who made me feel like I was having an honest conversation, as opposed to a cold and impersonal interview.

First-round was phone screening, where engineering from the team called and asked about the project which I have recently worked on, and also asked questions on a basic algorithm and their complexities. later asked questions on networking concepts like VLAN, STP, classful and classless addressing, and then write a code to determine the endianess.
