Cisco Software Developer interview questions

Took 5 rounds ,nearly 6 hours. Mostly networking and data structures. Was asked to write couple of programs based on arrays n hashing. Basic networking questions like packet flow , dead lock and synchronization mechanism. Questions based on IPCs like message queue, sockets.

Coding challenge was relatively easy for me with no DS&A experience. I didn't do perfectly, but I did much better than I expected given the difficulty of leetcode. I am awaiting feedback on my coding challenge.
