Cisco coding interview / online assessment, format and difficulty (2026 update)

Applied for a new grad SWE role at Cisco San Jose this spring. Here's the full breakdown of the coding rounds because I couldn't find recent info anywhere.

Online Assessment (OA): two coding problems, 75 minutes total. Platform was HackerRank. The first problem was a graph traversal question involving network topology, basically BFS to find the minimum hops between nodes under certain constraints. The second was a string manipulation / regex-style parsing problem. Both were medium difficulty on LeetCode scale. Nothing I'd call hard. Test cases were visible for the first problem, hidden for the second.

I had about 5 days to complete the OA after the recruiter sent the link.

Phone Screen (technical): one coding problem on a shared editor (CoderPad), 45 minutes. The interviewer was a senior SWE. Problem was a two-pointer / sliding window question on an array of packet sizes (again, networking-adjacent framing). He asked me to walk through edge cases before coding, which I appreciated. I was able to finish and he had about 10 minutes of follow-up questions about time and space complexity plus one variant of the problem.

Difficulty compared to big tech: honestly easier than Google/Meta in my experience. The problems have networking flavor (graphs, packet data, routing tables) but the algorithmic depth felt like mid-tier LeetCode. If you've done 50-100 mediums you'll be fine. Don't skip graph basics, DFS/BFS came up twice across my rounds.

I did end up moving to the onsite after this. Total time from OA invite to phone screen was about 3 weeks. Cisco's recruiting pace is slower than startups but they actually communicate, which I appreciated as a new grad because the ghosting elsewhere has been brutal.

Happy to answer questions about specific questions if it helps anyone.

This is exactly what I was looking for. Do you know if the OA uses a webcam proctoring setup or is it honor system? Some platforms get really annoying with lockdown mode.

No proctoring camera, just the HackerRank platform. No lockdown browser. They do have code similarity detection though so obviously don't copy-paste from anywhere.

3 weeks between OA and phone screen sounds about right for Cisco. Their process is methodical. The flip side is you actually get real feedback when you don't move forward, at least in my experience, which is more than I can say for most companies in 2026.

Interesting that the problems have networking flavor. On the hardware/embedded side at Cisco the technical screen is completely different, more low-level system stuff and signal processing concepts. Makes sense they'd tune the SWE version to their domain too.
