Round 1 ( Technical Interview, 60 min)
- The interview started with my intro, and then he asked me to explain one of the projects that is written on my resume
- In that project, I used bcrypt for password hashing, so he asked me to develop my hashing function, and asked me to give an algo for that... and after that, because i have some experience in backend development, he gave me a scenario where I have to give an approach to develop some feature.
- after that, he gave me a coding problem which is based on oops. ( in this question I have to write a program to find the number of objects created by a class, at any point of time)
- what is the diff between a static function and a static variable, given two scenarios where a function is static and a variable is not, and in another one, the function and variable both are static, what is the diff between the two scenarios...
- after that, he asked me some basic DSA concepts like: what is BST, gave me a real use case of it, etc...
- Another question from programming: how you can include a cpp file in another cpp file to use those functions or variables which is declared in that file, that we want to include?
- Then, he asked me some computer network questions... like when we type "www.google.com" in our browser our browser responds to us, what are the intermediate steps in this complete process, and how they work...
- what is the Diff between TCP and UDP, which is better in which case..
- The last question was about OS, if a parent calls his child process and the parent is terminated before his child then what happens with the child.....
Round 2 ( Manager Round, 45 min)
- The interview started with my intern's explanation, and then he asked about the tech stack that I used and some basic questions on functionality that I have developed.
- after that, he asked some SRQ questions
I couldn't make it to the next round, but I’m sharing this in hopes that it may help you in your Cisco interview. One piece of advice I’d like to offer is to thoroughly cover Operating Systems, Computer Networks, and Object-Oriented Programming before the interview
