Cisco's online assessment is commonly reported as a HackerRank test that mixes one to three coding problems with multiple-choice questions on networking, operating systems, databases and aptitude, especially for campus and early-career roles. Some US intern invitations are coding only, so the mix depends on the role and the hiring drive. This page covers what the Cisco online assessment is, its format and timings, how it is scored, the rules to know before you start, how to prepare and a two-week practice plan.
What the Cisco online assessment is
Cisco's hiring pages say some positions require a pre-employment assessment through one of its testing partners, but Cisco publishes no format, so this page reflects candidate reports and guides checked on November 12, 2026. India campus and new-grad reports describe a long multiple-choice section, often about 40 questions, beside two coding problems; one 2027-intern campus account described 42 questions in 90 minutes, and a 2025 consulting-engineer report described 59 scenario-based multiple-choice questions with one coding problem. US intern reports more often describe two or three LeetCode-style problems and no multiple choice. Cisco's own GenAI guidance for candidates lists generating a scripted response to complete an assessment, and generating a coding solution in real time, as not permitted, while allowing AI for preparation tips and brainstorming approaches beforehand.
Because networking questions are what set Cisco's test apart, revise with computer networks interview questions and operating system interview questions.
Format and timings
| Part | What it involves | Time and questions |
|---|---|---|
| Coding problems | One to three problems; graphs, BFS and shortest paths, tries and dynamic programming come up often | Shared time limit |
| Networking multiple choice | OSI and TCP/IP layers, subnetting and CIDR, routing, TCP versus UDP, DNS and DHCP | Part of a section that often runs to about 40 questions |
| CS fundamentals multiple choice | Operating systems, DBMS, object-oriented programming and C output questions | Same section |
| Aptitude (many campus drives) | Quantitative and logical reasoning | Same section in some drives |
Total: commonly reported as 60 to 90 minutes; one compilation gives up to 120 minutes for some drives. Your invitation states the real limit.
How it is scored
- Coding problems are auto-graded on hidden test cases, and partial passes usually count.
- Multiple-choice items are scored on accuracy; negative marking is not commonly reported for Cisco, but check the first screen.
- Cisco publishes no cut-off; one candidate reported waiting about a week for results.
Rules to know before you start
- Cisco's candidate guidance says submissions must reflect your own skills and efforts; generating answers or code with AI during an assessment is not permitted.
- HackerRank lets employers turn on full-screen mode, tab-switch warnings, copy-paste blocking and webcam monitoring, and your invitation tells you which apply.
- Campus candidates usually test in a drive scheduled through the placement cell, so the window is short.
- Use a laptop on a stable connection; the test is not built for phones.
How to prepare
- Revise subnetting until you can split a /24 network by hand, then the OSI layers and which protocol lives where.
- Practice graph problems in your test language: BFS on grids, Dijkstra and topological sort.
- Do short timed multiple-choice sets on operating systems (scheduling, deadlock, paging) and DBMS (normalization, joins, transactions).
- Campus candidates: add 15 minutes of aptitude practice a day.
- Simulate the full mix: about 40 multiple-choice questions and two coding problems in 90 minutes.
A two-week practice plan
- Days 1 and 2: read the invitation or drive notice, list the sections and try HackerRank's sample test.
- Days 3 to 5: networking every day: layers, subnetting, TCP and UDP, DNS and routing, with 20 timed questions a session.
- Days 6 and 7: operating systems and DBMS multiple choice, plus C and object-oriented output questions.
- Days 8 to 10: two coding problems a day on graphs, tries and dynamic programming.
- Day 11: aptitude sets if your drive includes them, or extra graph practice if not.
- Day 12: one full mock of 40 questions and two coding problems in 90 minutes.
- Day 13: review every wrong answer, then rest.
- Day 14: take the test early in the window.

On the day, and the mistakes to avoid
- Check the invitation for the platform, the sections, the time per section and whether wrong answers cost marks.
- Try the platform's sample test so the editor, run button and question navigation are familiar.
- Use a reliable laptop on a stable connection, with a working webcam if the invitation asks for one, and close other apps and tabs.
- Note whether sections are timed separately; time left in one section may not carry over.
- Answer the multiple-choice items you know quickly, flag the rest and protect time for the coding problems.
- Before submitting code, run your own edge cases and remove debug prints.
Mistakes that cost candidates:
- Spending the whole clock on one coding problem and leaving easy multiple-choice points unanswered.
- Guessing on every multiple-choice item in a test that uses negative marking.
- Revising only LeetCode and skipping the C output, pointer and operating-system questions.
- Submitting a brute-force solution that passes the samples but times out on hidden tests.
- Switching tabs or windows in a monitored test, which can be logged.
What happens after the Cisco online assessment
Shortlisted candidates commonly report one or two technical interviews, often on Webex, covering coding, networking and projects, then a managerial round and a short HR conversation. Guides put the whole process at two to eight weeks, and experienced hires may skip the assessment and start with a recruiter. For the next stage, see our technical phone screen guide.
Where CoPilot Interview fits
Online assessments are tests you take on your own: outside help is not allowed, and proctoring settings can flag other apps, tab switches or a second voice. Practice beforehand instead. CoPilot Interview is an AI interview assistant; its free AI mock interview prepares you for the interviews that follow the assessment, with questions built from your résumé and the job description and each spoken answer scored out of ten. The free plan gives 15 minutes a day of live help in sessions of up to 15 minutes, with AI mock interviews included. Read the invitation carefully and follow your employer's rules.
Disclosure: CoPilot Interview is our product, so weigh what we say about it accordingly.
Frequently asked questions
Does Cisco use HackerRank?
Most candidate reports from 2024 to 2026 say yes; a few guides also mention CodeSignal. Your invitation names the platform.
How many questions are on the Cisco OA?
Commonly one to three coding problems plus about 40 multiple-choice questions, though some US intern tests are coding only and one 2025 report described 59 multiple-choice questions.
Are there networking questions on the Cisco test?
Yes, in most reports that include multiple choice: protocols, layers, subnetting and routing basics, beside operating systems and DBMS.
What does Cisco say about AI in assessments?
Its candidate guidance allows AI for preparation tips and brainstorming beforehand, but not for generating a scripted response to an assessment or a coding solution in real time.
Can I use AI tools during the Cisco online assessment?
No, unless the instructions explicitly allow it. Assessments are meant to be taken on your own, and proctoring settings can flag other apps, tab switches or pasted code. Use AI tools to practice beforehand, and follow your employer's rules.
Practice this interview before the real one
The AI mock interview builds questions from your resume and the job description, reads them aloud and scores each spoken answer out of 10. Included on the free plan.
