Cisco HackerRank Online Assessment: 2-3 Problems Plus 40 MCQs

Last updated: October 2026

Quick Answer

The Cisco HackerRank online assessment is a timed test sent to many engineering candidates before the live rounds: candidates most often report one to three coding problems plus about 40 multiple-choice questions on networking, operating systems, databases and OOP, in roughly 60-90 minutes. Some US reports describe coding only. Prepare the coding half in OphyAI Coding Interview and the spoken theory in OphyAI Interview Practice.

Part	What candidates report
Platform	HackerRank; Cisco says it uses “testing assessment partners”
Coding	1-3 problems: graphs, tries, dynamic programming
MCQs	About 40 in most 2024-2025 reports; one says 59
MCQ topics	Networking, operating systems, DBMS, OOP, some aptitude
Time	About 60-90 minutes; your invitation states the real limit
Next step	Technical rounds on Webex, then a managerial round

What Cisco Is Testing in This Round

Two things at once: correct code under a clock, and CS fundamentals. The Cisco interview guide explains why Cisco keeps a networking bar even for software roles; this is where it is applied first. Hidden test cases grade the code, and the MCQs count: one 2024 intern believed a strong MCQ section got them shortlisted despite weak coding.

Red flags that fail candidates:

• Passing the sample input but failing hidden cases (empty input, duplicates, disconnected graphs).
• Spending 40 minutes on MCQs and leaving the coding, which one 2025 candidate said carries more weight, half done.
• Knowing the OSI layers as a list but not where ARP, TCP or a router sits.

What to Expect

Cisco does not publish the format. Its How We Hire page says only that “some positions will require a pre-employment assessment through one of our testing assessment partners” and that your recruiter will tell you. Format details below are candidate-reported.

• Where the detail comes from. The fullest write-ups are from Cisco’s India campus and Code with Cisco drives. US Glassdoor reports for San Jose intern roles more often describe coding only, for example three LeetCode easy-to-medium problems. Prepare for the MCQ block anyway.
• Shape. A 2025 intern report: 40 MCQs on OOP, networks and operating systems, plus a trie-and-BFS problem and a graph problem. A 2024 report: 42 MCQs including DBMS and aptitude, plus a DP problem and a graph problem. A 2025 consulting engineer report: about 90 minutes, 59 scenario-based MCQs, one medium-hard problem.
• Proctoring. HackerRank lets each employer choose. Secure Mode enforces full screen, warns on tab switches, blocks copy and paste and allows one monitor. Proctor Mode adds webcam monitoring, phone detection and screen sharing.
• AI rules. Cisco’s hiring page says not to use AI to “generate a scripted response to complete an assessment” or to “generate a solution to a coding problem or design question in real-time”, while welcoming it for preparation. See our tracker of companies that allow AI in interviews.
• Next. Results took about a week in one report, followed by technical rounds on Webex.

Example Questions and How to Answer Them

Reported themes, not leaked questions.

1. A trie plus BFS problem

Approach: Build and test the trie alone first. Then BFS from the start with a visited set, and handle the no-path case.

2. A graph shortest-path problem

Approach: Adjacency list, BFS for unweighted steps, Dijkstra with a heap for weighted edges. Router-and-link stories are still graph problems.

3. A medium dynamic programming problem

Approach: State the subproblem in one sentence, write the recurrence, then the base cases. Memoized recursion that passes most cases beats an unfinished table.

4. A subnetting MCQ

Approach: Know CIDR cold: a /26 has 64 addresses and 62 usable hosts. Also know the private ranges and what a default gateway does.

5. An operating systems MCQ on deadlock

Approach: Learn the four Coffman conditions (mutual exclusion, hold and wait, no preemption, circular wait) and which prevention strategy breaks each.

How to Prepare in 3 Days

• Day 1: fundamentals. Networking (layers, TCP versus UDP, the handshake, ARP, DNS, subnetting), operating systems (threads, deadlock, paging) and DBMS (normal forms, joins, indexes). Finish with 40 timed MCQs in 30 minutes.
• Day 2: timed coding. Two sittings of two problems in 60 minutes from graphs, tries and DP; our coding interview examples and solutions has sets. After each timer stops, review missed approaches in OphyAI Coding Interview on Premium, which fits Cisco’s “brainstorm multiple approaches” guidance for preparation.
• Day 3: mock and logistics. One full sitting with MCQs capped at 30 minutes. Check the invitation’s time limit, languages and proctoring, and test your webcam. Then run a technical mock in Interview Practice so you can explain DNS aloud for the Webex rounds.

Common Mistakes

• Treating it as coding only. Networking MCQs sink pure LeetCode preppers.
• Breaking integrity settings. Leaving full screen or pasting code gets logged.
• Using AI during the test. Cisco’s own page rules it out; keep AI to preparation.
• No MCQ time budget. Cap it, flag hard questions, move on.

Frequently Asked Questions

How many questions are on the Cisco HackerRank assessment?

Most 2024-2025 candidate reports describe about 40 multiple-choice questions plus one to three coding problems, with 42 in total a common figure. One 2025 report describes 59 MCQs and one coding problem, and some US intern reports describe three coding problems and no MCQs. Cisco publishes no fixed count.

How long is the Cisco online assessment?

Reports range from about 60 to 90 minutes, and one compilation of candidate write-ups gives 60-120 minutes depending on the drive. Plan for 90 minutes with about 30 on the MCQs, and rely on the limit printed in your own invitation, which HackerRank shows before the timer starts.

Is the Cisco HackerRank test proctored?

Some third-party prep guides describe a proctored test, and HackerRank lets each employer choose. Secure Mode enforces full screen and disables copy and paste; Proctor Mode adds webcam monitoring, phone detection and screen sharing with a session replay. The pre-test screens tell you which apply.

Can I use ChatGPT or other AI on the Cisco assessment?

No, by Cisco’s own guidance. Its How We Hire page says not to use AI to generate a scripted response to complete an assessment or to generate coding solutions in real time. The same page welcomes AI for preparation tips and brainstorming approaches, so use it to practise beforehand, not during the test.

What happens after the Cisco online assessment?

Shortlisted candidates report one or two technical rounds on Webex mixing resume projects, DSA and networking, then a managerial round and a short HR call. Cisco may ask for a resume in its own anonymized format first. The Cisco interview guide covers those rounds and the 2-8 week timeline.

Sources and verification notes

Checked October 2026. Cisco, HackerRank and GeeksforGeeks pages were opened directly; Glassdoor blocked fetches, so the US coding-only reports came from search summaries. All format details are candidate-reported.
