Cisco Software Engineer interviews typically run 3–4 rounds: online assessment, recruiter screen, technical interviews, and a managerial or HR round. The process spans roughly 3–6 weeks and is distinguished by its heavy emphasis on networking fundamentals alongside standard DSA coding questions.

What strikes us most across Cisco's Software Engineer interviews is how consistently the process tests two things at once — and candidates who prepare for only one of them tend to get caught off guard. Multiple candidates reported that networking fundamentals showed up even in roles that looked purely software-focused on the job description. We're talking OSPF, BGP, TCP/IP layers, ACLs, layer 2 vs. layer 3 switching — not just buzzwords, but applied understanding. One candidate was asked to explain what happens when you connect to Wi-Fi; another got questions on MPLS and QoS. If you're coming from a pure software background and skipping the networking prep, that's a real risk here.
The second filter is resume depth. Nearly every candidate who made it past the OA described at least one round that was essentially a structured walkthrough of their own experience — not a casual chat, but a detailed interrogation of what they actually built, what decisions they made, and why. One candidate lost an offer in part because they had written pseudocode instead of runnable code and couldn't debug it on the spot — a small but telling detail about what Cisco actually values. They want to see that you can execute, not just explain.
The coding bar itself is relatively approachable — easy to medium LeetCode, classic patterns, occasionally a concurrency or system design question — but the process has real variance. Some candidates hit Java multithreading and producer-consumer problems when they expected system design; others saw Python flexibility tested mid-interview when they'd chosen C++. We've seen candidates rejected at the OA stage within a week and others sail through a full loop. The throughline is this: know your resume cold, brush up on core networking, and be ready to write code that actually runs.

The first round was basically all resume and project discussion, and that set the tone for the whole process. They really wanted me to know my own background in detail, not just give a high-level summary. After that, I got a very simple DSA question, I think it was palindrome related, nothing too hard but they were checking whether I could explain my thinking clearly. That part went well, so I felt good going into the next round.
The second round was with a manager who had been at Cisco for a long time, and it was again very focused on my resume. He spent a lot of time talking through my experience and then gave me another easy DSA-style question. The one thing that caught me off guard was that he asked me to run the code after I had written it, and I had only typed pseudocode, so it didn’t work and I couldn’t fix the error on the spot. He was still calm about it and said he mainly wanted to see how I thought, which helped. The next round was only about 10 to 15 minutes and felt almost like a formality. They asked if I was open to relocation and checked whether I knew the details of my internship. I thought that round went fine too, but in the end I was not selected. From what I experienced, the process was mostly resume-heavy with one simple coding question per round, and the biggest lesson is to be ready to actually execute what you write, not just explain it.
Prep tip from this candidate
Be ready to defend every line on your resume and internship details, because they spent a lot of time drilling into that. Also, if you write code in the interview, make sure it is runnable, since I was asked to execute mine after I had only given pseudocode.

Synthesized from candidate reports. Individual experiences may vary.
Candidates typically receive an online coding assessment shortly after applying. It consists of 2–3 LeetCode-style problems ranging from easy to medium difficulty, sometimes accompanied by CS multiple-choice questions covering fundamentals. This serves as an initial filter before any live rounds.
A recruiter or HR representative reaches out to discuss the role, confirm logistics such as location and availability, and ask basic motivational questions like why you want to join Cisco. This round may also include a brief overview of your background and experience.
A live technical conversation, sometimes with a hiring manager or senior engineer, covering resume walkthrough, easy-to-medium DSA problems, and foundational CS topics such as networking, operating systems, or OOP. The interviewer typically cares as much about how you explain your thinking as whether you reach the correct answer.
One or two deeper technical rounds covering LeetCode-style coding problems, core CS fundamentals (networking concepts like TCP/IP, OSI layers, OSPF, BGP; OS topics like memory management and processes; and language-specific questions in C, C++, Java, or Python), and sometimes system design or practical lab-style scenarios. Interviewers expect clean, executable code and clear reasoning.
A conversation with a manager focused on resume deep-dive, past project contributions, architecture decisions, and behavioral questions about challenges faced and teamwork. Career expectations and team fit are also assessed in this round.
A short closing conversation with HR or an ETR representative that functions primarily as a fit and logistics check. Questions are light and the round typically feels like a formality before a final hiring decision is made.
