The Cisco Interview Process

Before we look at the ideal 2-month Cisco interview preparation plan and sample Cisco interview questions, let us first understand what the technical interview process at Cisco looks like.

The Cisco interview process essentially tests your ability to solve complex coding problems and build arbitrary, scalable systems with low latency. The three main rounds of the process include –

• The Recruiter Screen – This is a basic interview round where a recruiter will call you to understand your interest in the position. You’re typically asked questions about your work experience, professional skills, past projects, and your expectations from the role.
• The Technical Phone Screen – This round evaluates your ability to solve core DSA problems of medium difficulty. The round typically lasts about 30 minutes via a shared document or a remote interviewing tool.
• The On-site – The on-site interview consists of a coding, design, and behavioral round. Depending on the seniority of the position you’re applying to, there could be additional design or leadership interviews. The on-site interview is the real test of your problem-solving and design capabilities.

The Ideal 2-month Cisco Interview Preparation Plan

Let’s go ahead and look at what the ideal Cisco technical interview preparation plan should look like.

Week 1 and 2

• Spend the first couple of weeks solving problems in core data structures. Go through arrays, sorting algorithms, strings, and linked lists.
• Enroll in a good interview prep course to get insights and guidance on cracking technical interviews.
• Start practicing at least 1-2 problems every day. Make sure to classify problems based on identical solution patterns and use analogous patterns to approach and solve new problems.

Week 3 and 4

• Core data structures and algorithms should continue to be the focus. Move onto trees, graphs, recursion, hash tables, and dynamic programming.
• Start taking regular timed tests – at least once a week – to prepare yourself in an interview-style environment.

Week 5 and 6

• Start preparing for your systems design interview.
• Start by understanding the design behind popular scalable platforms.
• Brush up on essential design concepts such as online processing systems, sharding techniques, file systems, and loading.
• Continue solving one or two coding problems and revise design concepts, including Concurrency, Network Protocols, and API modeling.

Week 7 and 8

• Practice mock interviews with expert professionals. With Interview Kickstart, you can practice mocks with FAANG hiring managers and instructors who are members of the hiring committee at top technology companies.
• If you are preparing for a domain-specific interview, practice mock interviews in your domain. With IK, you have the unique opportunity to practice domain-specific mock interviews across 17 different software engineering domains.

Week 9

• Optimize your LinkedIn profile and resume. Spend the week understanding behavioral interviews and the type of questions asked.
• Practice answers to commonly asked behavioral interview questions. Make sure to structure your answers in the STAR format to give recruiters a clear picture of your experiences.

Cisco Interview Questions on Coding

In this section, we’ll look at some Cisco interview questions on coding. Before that, here are the important coding topics to prepare for the interview:

• Arrays, strings, and linked lists
• Trees and graphs
• Recursion
• Sorting algorithms — quicksort, merge sort, heap sort, etc.
• Dynamic programming
• Graph algorithms, including greedy algorithms

Let’s go ahead and look at some sample Cisco interview questions on coding.

1. Write a program to count the occurrence of a character in a given string S.
2. Write a code to print the first non-repetitive character in a given string S.
3. Explain how the Radix sort algorithm is used and implemented.
4. Write a code to print the duplicate elements in a given array A.
5. Explain how the Iterative QuickSort algorithm is implemented through a program.
6. Write a code to print the bottom view of a given binary tree from left to right.
7. Write a program that identifies the strongly connected components in a given Graph.
8. Write a program to find the length of the longest substring. Make sure the characters are not repeated.
9. Explain how the Binary Search Tree is implemented through a program.
10. Explain how you would traverse a binary tree in postorder without recursion?
