talk about Cisco, really is one of the big brothers of the American technology companies, every year in the technology research and development of more than 4 billion U.S. dollars, almost all the innovation in the field of network and communications it led. glassdoor on the data show that the Cisco research and development post the average annual salary of roughly 188,000 U.S. dollars, the base salary, allowances, bonuses and stocks are counted, the treatment is really very fragrant.
Recently, the students we took successfully passed the Cisco interview and took the offer, and the whole process was very smooth. This also shows that advance preparation and targeted guidance can really help you stabilize the rhythm in the interview, less stepping on the pit, more points.
Cisco OA
The Cisco Online Assessment is usually conducted via HackerRank or Codility and consists of 2-3 programming questions + several multiple choice questions (logic/CS based).
The overall length is in 75 to 90 minutes, the exact form depends on the position:
- Software Engineer / SDE / Intern: Algorithms + Programming implementation + some CS concepts.
- Data / Analytics related positions: SQL + Python + statistical logic questions.
- Network / Security Position: Multiple choice questions favor basic network knowledge.
Cisco OA 1
You are given an N*M matrix and told to rotate it 90 degrees clockwise and then print it out by rows. brute force does this by opening up another new M*N matrix and filling it in one by one and then printing it out in layers. But the question doesn't really ask you to rotate a matrix, otherwise you'd have to waste M*N space and time. Look for the law can be found, the equivalent of you directly from the lower left corner to the upper right corner of such a column to print the original matrix, so that the space complexity O(1), the time complexity can also save half.
Cisco OA 2
Give you a bunch of horizontal and vertical coordinates pairs, you can only fly horizontally or vertically, and can only fly once (similar to the chicken jump parachute, but can not fly diagonally), ask you can go through the most coordinates are a few? This question set of armor, dismantle the armor to see in fact is to ask you to appear in the horizontal coordinates of the most value1 is how much (that is, vertical flight), as well as vertical coordinates of the most value2 column is how much (that is, flying horizontally), and then print out the value1 and value2 in the largest one on the line. It's easy enough to do with a HashMap to record the horizontal/vertical coordinates and frequencies.
Cisco OA 3
Given integers X and Y, find the number of integers that are less than X whose digits sum up to Y.
Cisco VO
Cisco's VOs are usually divided into 1~2 rounds of technical interviews + 1 round of HR interviews, with slight differences depending on the position (SDE, Data, Network, Security, etc.).
First round Technical interviews
The first round consisted of some operating system-related questions after introductions, followed by some technical questions that dealt with computer network fundamentals, some operating system concepts, and two important features of object-oriented programming (inheritance and abstraction).
Coding是编写一个递归函数，使用递归打印从 1 到 100 的数字，传递的参数为 100；解释了一下递归堆栈；还额外提了一个基于 DSA 的二叉搜索问题，有点难度。
Round 1 Technical + Management Interviews
The second round was technical + managerial, where a data structure would be designed for a specific case, and about 70% of the time was spent discussing my project after the build idea was presented.
The interviewer asked quite a lot of scaling questions and we delved into scaling optimization and some exceptions. The interviewer would go into deeper discussions all the time. After that it was a very simple conversation like what is the best example of explaining networking concepts to a layman, why did you choose Cisco and so on;
Third round HR
The last round was HR round This round was basically BQ and some position questions, asked some personal questions and BQ was some common questions:
- What do you know about Cisco?
- Competitors of Cisco.
- Products of Cisco.
- Current affairs related to the company.
