Jio is having one of the most robust and fast pace interview process. Jio came to our campus for the position Of Graduate Engineer trainee and the job profile was of a data scientist.
Round 1 There was a online round of 50 minutes and five section 10 min each and the topics were Big Data, Hadoop, RadioFrequency, Java and C++, Aptitude . The question were multiple choice. After this round 5 out of 10 were shortlisted.
Round 2 Jio recruiters came to our campus and held a pen paper coding round of 30 minutes. This was not an elimination round but based on this you will be asked questions in face 2 face round. There were total 5 question. Write code to print mirror image of a tree Write code to add two very large number basically you had to use two linked list find maximum sum sub-array from an array of pos and neg integers find length of a loop in a linked list You have been given a rectangle that was split into small squares of fixed size. Two circles with radii r1, r2 was drawn inside the rectangle you need to find the center of the square in between the region of circles.
Round 3 The panel had four members one of the member was from data science background . It’s not necessary that you should be having a data science background they were only asking questions on the things you claim you know from your CV. DS->Interviewer from datascience dept, Al->Interviewer from Algo dept Interviewer (DS): Tell me about your strength Me: I am basically a full stack developer (MEAN stack) web and Android Developer. Interviewer (DS): Question regarding GET, PUT, POST and projects done using MEAN stack. ME : Answered with confidence as this was my area. Interviewer (DS): Difference between java and c++ , Have you ever used any machine Learning in your projrct ME : answered using procedural vs object oriented programming and told my face recognition project were i used ML techniques (Questions : what is SVM, How did you made your classifier, What feature you used) Interviewer (DS): Write the formula of conditional probability and also how you will compute eigen values of a Matrix. Me : This is were the trouble began . I didn’t remember the formula so after 2–3 min i wrote the formula for Bayes theorem(another form of conditional prob) and gave the approach to find eigen vectors(He was more or less satisfied). Interviewer (AL) : You have not written much in the coding round. Me : ( are you kidding the time given was only 30 min and i have attempted 3 out of 5 ) sir i have attempted 3 questions and had written approach for 4th(mirror tree) . Then he went through my answers and told me to code the approach . After 5–8 minutes i wrote an recursive approach he went for the dry run and was satisfied. Interviewer (AL) : You have also not completed the code for 4th question . Me : (I had misinterpreted the question instead of finding loop length i founded the list length ) Sir i have completed it and gave him the approach and that is were i found out that i had misinterpreted the question. He told me to correct the approach . Me after 1 min gave him the right approach and he was satisfied. Interviewer (AL) : What all sorting algorithms you know Me : Bubble, Insertion, Quick, Merge (interrupt) Interviewer (AL) : Told me to code the Merge Function used in the merge sort . Me : I gave my approach and he was satisfied so no need to code. Interviewer (HR) : how much % you achieve in math (10 and 12th), JEE rank, Why should we hire you. Me : During my 4 years of academics I have found 1 strong ability in myself that i do not get stuck on any problem by some hook or crook i was able to tackle the problem (That is why you should hire me . This was not a prepared answer it just happened on the spot .He was satisfied). Finally the result announced out of 5 three were selected i was one of them. I would like to thank GeeksForGeeks for helping me to gain knowledge and crack the interview.

About Reliance Interview Reports
This question was reported by a candidate who interviewed at Reliance. 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 Reliance are the higher-signal extractions to take from this report.
For broader preparation context, the Reliance 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 Reliance reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Reliance 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 Reliance 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.
