Cisco Interview Expertise for Internship 2022-23 (On-Campus) Digital


Cisco just lately visited the IIT BHU campus to supply a 2-month internship for the upcoming summer season of 2023. An internet coding spherical was performed on hacker rank. The spherical consisted of two coding issues together with 40 MCQs. Round 700 college students appeared for it.

On-line coding Spherical (1 hour half-hour): The entire generally used coding languages resembling C++, C, Python, Java, and so on have been accessible. This spherical consisted of 40 MCQs and a couple of Coding issues and we have been allowed to easily navigate between the questions.

  • Coding issues: 1.) Query was primarily based on Floyd Warshall algorithm / Dijkstra’s algorithm. 2.) This query was additionally primarily based on Graphs and on this we have been requested to put some towers on nodes of a graph such that every node could have a tower or any adjoining node having a tower. We have been requested to output a minimal variety of such towers.
  • MCQs: There have been 40 MCQs and have been primarily based on matters like Aptitude, OS, OOPs, and Laptop Networking.

Verdict of On-line spherical: 40 college students have been shortlisted for interviews.

Acing Strategies: You need to have information of the basics of Computer systems and a few primary information of networking.

I had 3 Interview Rounds (2 Technical and 1 HR) after qualifying on-line spherical.

Observe: Should you don’t have any concept about networking, you possibly can nonetheless clear the interview. Simply let the interviewer know that in the beginning of the interview with some legitimate causes (not but taught within the curriculum), having some information of CN will certainly give you an edge over others.

Technical Spherical 1: (Length 50 minutes): The interviewer requested me to introduce myself. He needed to know my tech stack and my areas of curiosity. Let me inform you, networking was not taught to us until the 4th semester, however i a couple of primary ideas of laptop networking and this actually helped me edge over different college students who weren’t conscious of laptop networking. As he received to know, that I’ve an curiosity in networking, he requested me what issues I’ve explored as of now. Then he requested me to elucidate the time period networking and the kinds of networks. He then requested me about Peer to Peer and Shopper-server networks. He additionally requested me to elucidate the benefits and drawbacks of each of them. He additionally requested me for an instance of peer to see community in actual life. He additionally requested me about layering and switching in Networking. He requested me in regards to the layering sample that works within the functioning of Google Chrome. Then we had venture discussions. Then he requested me to inform some cases of networking in OS. He requested me in regards to the OS that I take advantage of. Then he requested me to elucidate varied strategies of inter-process communication strategies between processes in OS, Working strategies of the message queue. Then he requested me, about my favourite information construction and I replied to the tree, Then he requested me about some issues associated to timber. He additionally requested me to inform the STL container that makes use of timber in its inner implementation. He additionally requested about the potential of looking out a quantity in O(1) complexity with any house complexity. Then we’ve got some dialogue on Knowledge constructions and algorithms. No OOPs have been requested of me on this spherical. Ultimately, he requested me, that if I had any questions for him.

Verdict: 26 college students certified for Technical spherical 2.

Technical Spherical 2: (Length 60 minutes): This spherical additionally began with my introduction of mine. He requested me to elucidate my initiatives, their implementation, and what new points they clear up. I had one venture as an e-commercial web site that was primarily based on the Django backend. He requested me how, my web site is totally different from Massive websites like Flipkart, Amazon, and so on. He then requested me to elucidate the time period “working system” to a layman. He requested me to elucidate the time period semaphore and busy ready. He requested me to elucidate busy ready utilizing real-life examples. He additionally requested me about mutex locks and paging strategies in OS. I let him know that I’ve an curiosity in laptop networking. He then requested me the next questions in CN:-

  • Distinction between switches and routers.
  • Transient working of routers
  • Layers in OSI reference mannequin
  • During which layer routers and switches are current within the OSI mannequin?
  • Functioning of some layers of the OSI mannequin.
  • Varied lessons in IPV4 addressing.

Following DSA questions have been requested:-

Following OOPs, questions have been requested:-

  • Distinction between shallow copy and deep copy in oops.
  • Distinction between copy constructer and duplicate task operator.
  • Clarify inheritance with real-life examples.
  • Clarify the lethal diamond of demise drawback and its resolution.
  • Clarify the benefits and drawbacks of OOPs.

Puzzle:

  1. https://www.geeksforgeeks.org/puzzle-7-3-bulbs-and-3-switches/

He then requested me whether or not I’ve any questions for him.

Verdict: 16 college students certified for the HR spherical.

HR Spherical: Length(10 minutes): The spherical was largely informative. I used to be instructed in regards to the stipend, and the work anticipated of a summer season intern and requested about my initiatives and former internships. (As a tip, make sure that you could have some information in regards to the firm). He requested me a couple of questions:

  • Identify some opponents of Cisco.
  • Inform any 2 present affairs associated to Cisco.
  • Co-curricular issues I do.
  • Pursuits
  • Choice order for the situation of internship (Bangalore, Pune, Chennai, and Hyderabad). Then he requested me, why I opted for Bangalore as my first desire.
  • Any questions?

Verdict: 8 college students have been lastly chosen. And happily, I used to be one among them.

Some suggestions:

  • Be common with coding (Simply apply extra).
  • For acing OOPs, and OS-related issues learn GFG articles completely.
  • Full all puzzles accessible on GFG.
  • Ultimately place confidence in your self and almighty god.

Good Luck!
