After the training we had 10 days of gap and then we had our interviews . My interview slot was from 9 am to 6 pm and we will be called randomly anytime in that given slot . We will be told to open our superset accounts and will be told to be online and when we get the interview call we have to accept it . There will be two interviewers ( one in person and another interviewer will be joined in the superset interview call ) Coming to the interview ... both the HR interview and technical interview has been conducted at the same time ( not sure if this is same for everyone because from what i have read online the HR and technical interviews were conducted at different days for few) . The interviewer first asked for my self intro ( keep it simple by just telling them your name , your skills and your projects ) 1 . Did you give any bribes to anyone in this company for this job? (I don't even know if that's a reasonable question for a student but yeah anyways.. ) 2. Why Cognizant? Do your own research about the company before the interview and try to give a good straight to the point answer so that you can make a good impression by letting them know that you are not just giving this interview because of the reputation of the company . 3. Can you tell about Java features? 4. Datatypes in Java? 5. What are wrapper classes? 6. What is Autoboxing and Unboxing? 7. Program : Take two ArrayLists , add elements to the ArrayLists , add the common elements in both of the ArrayLists to another ArrayList and print it . 8. What happens if we write the main class as "private class Main" instead of public ? Will it run ? If not , why ? 9. Can you tell the difference between "private" and "default" ? 10. Difference between abstract classes and an interface ? 11. Difference between "==" and ".equals( )" ? 12. What does "Scanner" do ? 13. How to do a delete operation in SQL ? 14. Can you tell some Object methods ? 15. Can you explain any Design pattern ? 16. What is Hibernate used for ? 17. Where are String Literals stored in Java ? 18. Can you relocate to any location given for you ? Do you have any preferred locations ? 19. Since we will be working with foreign clients there is a chance where you will have to work at different time standards .. most of the time it does not happen but can you work if you have to ? My interview ended here and i might have missed few questions . I have answered 80% of the questions and I am waiting for the results . Tips for my dear fellow students : Guys from whatever experience I got from this interview I can give you some little suggestions that may help you a lot . Interviewers don't look for students who know the basics of deep concepts . They look for the students who have deep knowledge in basic concepts . Listen guys .. we are freshers and it's ok to not know everything and its ok if you have low CGPA than other students who got selected for this interview . You don't have to have more knowledge than all of the students who got selected . Your CGPA and all of that only matters for the shortlisting and for the interview you just have to be thorough with the things you have learnt . So search of most asked interview questions online and test yourself how many you can answer . If you are unable to answer any of them . Just learn them now!! Its ok , its never too late . Open your book , search for most asked basic Java interview questions , write the answers in your book , learn them and practice the programs well . DO NOT SHOW THE INTERVIEWER THAT YOU ARE TENSED !! Be confident .. Because you and I know that you have given your everything for this interview and that you have prepared well . So why get tensed ? YOU GOT THIS ! YOU WILL CRACK THIS INTERVIEW FOR SURE ! Finally CONGRATULATIONS for getting selected for the interview and ALL THE BEST for the interview . Do well ! Will be grateful if this post helped you guys . - a fellow graduate .

About Cognizant Interview Reports
This question was reported by a candidate who interviewed at Cognizant. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.
Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at Cognizant are the higher-signal extractions to take from this report.
For broader preparation context, the Cognizant interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.
How To Practice This Type of Question
Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.
Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in Cognizant reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Cognizant Round
Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.
The single most predictive failure mode in Cognizant reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
