The candidate described an on-campus assessment, technical interview, managerial interview, and short HR conversation. Cisco teams and experienced-hire loops may differ substantially.\n\n## Online assessment\n\nThe candidate reported 40 multiple-choice questions on OOP, networking, and operating systems, plus two coding questions described only as a Trie/BFS problem and a graph problem. Since the statements were not published, they are recorded as topics rather than rewritten into questions. The details are in the [Cisco Summer Intern 2025 experience on GeeksforGeeks](https://www.geeksforgeeks.org/interview-experiences/cisco-interview-experience-for-summer-intern-2025/) (2025).\n\n## Technical interview\n\nThe interview included project discussion and these named prompts:\n\n1. What are network topologies, and how do physical and logical topologies differ? ([source](https://www.geeksforgeeks.org/interview-experiences/cisco-interview-experience-for-summer-intern-2025/))\n2. Explain FTP and active versus passive mode. ([source](https://www.geeksforgeeks.org/interview-experiences/cisco-interview-experience-for-summer-intern-2025/))\n3. How does DHCP work? ([source](https://www.geeksforgeeks.org/interview-experiences/cisco-interview-experience-for-summer-intern-2025/))\n4. What is a real-time operating system? ([source](https://www.geeksforgeeks.org/interview-experiences/cisco-interview-experience-for-summer-intern-2025/))\n5. How does a process differ from a thread? ([source](https://www.geeksforgeeks.org/interview-experiences/cisco-interview-experience-for-summer-intern-2025/))\n6. Explain starvation, deadlock, critical sections, and semaphores. ([source](https://www.geeksforgeeks.org/interview-experiences/cisco-interview-experience-for-summer-intern-2025/))\n7. Check whether a number is prime. ([source](https://www.geeksforgeeks.org/interview-experiences/cisco-interview-experience-for-summer-intern-2025/))\n8. Implement a linked list. ([source](https://www.geeksforgeeks.org/interview-experiences/cisco-interview-experience-for-summer-intern-2025/))\n9. Check whether a linked list is circular. ([source](https://www.geeksforgeeks.org/interview-experiences/cisco-interview-experience-for-summer-intern-2025/))\n\nThe questions are listed in the candidate's [Cisco report](https://www.geeksforgeeks.org/interview-experiences/cisco-interview-experience-for-summer-intern-2025/) (2025). The broader OS concepts in item six were presented as topics in the source, not a verbatim single interviewer question.\n\n## How to prepare for a Cisco software engineer internship interview\n\nThe next discussion revisited projects and networking. The candidate specifically reported explaining DNS end to end and discussing types of IP addresses. The conversation also covered a book and a student leadership role. The final short HR chat included strengths and weaknesses, teamwork challenges, and location preference. All appear in the [same Cisco account](https://www.geeksforgeeks.org/interview-experiences/cisco-interview-experience-for-summer-intern-2025/).\n\nThe report's practical lesson is to know the details of every project and resume line. For coding practice, work through linked-list operations without relying on a library. For networking, be ready to explain the path from a name lookup to a connection. These are candidate reflections, not an official Cisco rubric.\n\n## Frequently asked questions\n\n### What were the Cisco online assessment coding questions?\n\nThe candidate described them only as a Trie/BFS problem and a graph problem.
