Hour and a half of qustions ranging from past experience and projects to algorithmic task.Also questions about the internals of cpp,how compiling works etc. Good to know every project you listed on cv in depth,they will ask you.

First comes HR interview where you talk about yourself and the company's products. Then the first technical interview is onsite and you talk about your CV, projects, you answer theoretical questions (operation systems, object oriented programing, cpp in general) and then you get algorithm task (2 if you have time). You write on the board pseudo code and it should be optimized (but you can start with the brute force solution). Next round of technical is the same but you speak on English!

I came to the Cisco One site in Qesarya. I sat with two engineers and we introduced ourselves, they told me about Cisco. They asked me the LRU Cache question which is a LeetCode medium.
