CoCubes is an Indian campus assessment that companies configure from up to six sections: aptitude, computer fundamentals, a psychometric questionnaire, a domain test, coding and a written English essay. It belongs to Aon's Assessment Solutions, the same Aon unit that runs the former cut-e tests. This page covers what the CoCubes test is, its format and timings, how it is scored, the rules to know before you start, how to prepare and a practice plan.
What the CoCubes test is
CoCubes describes itself as an assessment and hiring platform for freshers, with a pool of more than three lakh pre-assessed candidates for employers. Your college's training and placement office usually registers you, you receive a CoCubes ID, and companies shortlist from your score. Prep sites name Capgemini, Bosch, Samsung, Adobe and Microsoft among companies that have hired through CoCubes, though drives and partners change from year to year.
Because Aon also runs the cut-e tests, some employers send Aon-branded tests instead; see our Aon assessment guide. CoCubes' candidate FAQ appears not to have been updated for several years, so treat its process details as a guide and confirm with your placement office.
Format and timings
| Part | What it involves | Time and questions |
|---|---|---|
| Aptitude | Numerical reasoning, logical reasoning and English usage | Commonly reported: about 45 questions in 45 minutes |
| Computer fundamentals | C, C++, object-oriented programming, data structures, networking and digital logic | Commonly reported: 15 minutes |
| Psychometric | Behavior and personality statements | Commonly reported: 12 minutes |
| Domain | Branch topics for CSE, IT, ECE, EEE, mechanical or civil | Commonly reported: 20 minutes |
| Coding | One to three problems in C, C++, Java or Python, run on visible and hidden test cases | Commonly reported: 30 to 45 minutes |
| Written English Test | One short essay of two or three paragraphs | Commonly reported: 25 minutes |
Total: about 2 to 2.5 hours if all six sections are enabled, as commonly reported; most drives use fewer sections.
How it is scored
- CoCubes' FAQ says 60 percent in each section is acceptable and an overall score of 550 or more is good.
- Sectional scores matter: CoCubes gives the example that an IT product role needs a medium to high coding score but may not need a high essay score.
- Shortlisting also uses company criteria such as 60 percent throughout your academics, your branch or your region.
- If you take CoCubes twice, the sectional best of the two attempts is used, according to its FAQ.
- No negative marking is commonly reported for standard configurations, but companies can configure it.
Rules to know before you start
- You can retake CoCubes any number of times, subject to slots, and you pay for each attempt.
- You can reschedule up to three days before the test; venue details arrive by SMS and email two days before.
- At test centres, staff check your details against a government photo ID.
- Once you apply for a company you cannot cancel, and missing more than two opportunities you applied for can lead to disqualification from future interviews.
- Your report reaches your email and CoCubes profile within two days of the test.
How to prepare
- Ask your placement office which sections your drive enables, then prepare only those.
- Practice a short structured essay with an introduction, two points and a conclusion for the Written English Test.
- Revise C, object-oriented programming, data structures and networking basics for computer fundamentals.
- Do easy to medium coding problems in one language and test edge cases, since hidden test cases decide the score.
- Answer the psychometric section consistently and honestly.
A practice plan
- Week 1: aptitude daily (quantitative, reasoning and verbal) with section timers.
- Week 2: coding problems of easy to medium difficulty in one language, plus pseudocode or technical questions if the test has them.
- Week 3: full mock tests under exam conditions and spoken-English practice if there is a communication round.

On the day, and the mistakes to avoid
- Keep your ID, admit card or invitation and academic documents ready, as the drive requires.
- For centre-based tests, arrive early and follow the centre's rules on phones and belongings.
- For online tests, check your camera, microphone and connection, and use a quiet room.
- Note each section's timer: sections are often fixed in order and you cannot go back.
- Attempt every question where there is no negative marking.
- In coding rounds, submit code that compiles and passes some cases rather than nothing.
Mistakes that cost candidates:
- Neglecting the English or communication section, which is often an elimination round.
- Overspending time in one aptitude section when each has its own timer.
- Practicing only coding and skipping pseudocode and computer fundamentals.
- Registering through unofficial links; use the company's careers site or your placement cell.
- Skipping full mock tests, so the real section timers come as a surprise.
What happens after the CoCubes test
Shortlisted candidates usually move on to technical and HR interviews, then an offer letter and onboarding. Prepare to explain your projects, basic programming concepts and why you want to join, and keep practicing spoken English for the interviews. For the next stage, see the new grad online assessment 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
Is there negative marking in CoCubes?
Not in standard configurations, according to prep sites, but companies can set it differently, so check your drive's notification.
What is a good CoCubes score?
CoCubes' FAQ says 60 percent in each section is acceptable and an overall score of 550 or above is good, though each company also applies its own sectional cut-offs.
How is CoCubes related to Aon?
CoCubes is part of Aon's Assessment Solutions, alongside the cut-e brand. Some 2026 prep pages describe it as part of another campus suite, which we could not confirm; CoCubes' own site still names Aon.
Can I retake CoCubes?
Yes, as many times as slots allow, with a fee each time. The sectional best of your attempts is used.
Can I use AI tools during the CoCubes test?
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.
