These are condensed from public candidate write-ups for Reliance Jio / Jio Platforms campus drives - the business unit most freshers on this page will actually face. The aptitude test is the sharp filter; after it, conversion rates are unusually high compared with product companies.
Reported background: MEAN-stack full-stack developer with web, Android and a face-recognition ML project.
Round 1 - Online test (50 min): five 10-minute sections - Big Data, Hadoop, RF, Java/C++, and aptitude. 5 of 10 candidates advanced. Note how role-specific the section list is; Jio tailors the test to the profile.
Round 2 - Pen-and-paper coding (30 min, non-eliminating): five questions used as material for the interview rather than as a cut. Mirror a binary tree; add two large numbers represented as linked lists; maximum subarray sum; find the length of a loop in a linked list; identify the centre of a circle inscribed in a square.
Round 3 - Panel interview: four panellists including data science and algorithms specialists plus HR. GET/PUT/POST; Java vs C++; SVM and other ML techniques; conditional probability; computing eigenvalues; writing the merge function of merge sort; sorting algorithms. HR asked about academic percentages and JEE rank.
Outcome: Selected - 3 of the final 5.
What both accounts share: the online test content follows the role, not a fixed syllabus, so read the placement email carefully. Interviews stay on fundamentals - OOPs, DBMS, SQL, one clean coding question - and your own project is the thing you will be pushed hardest on.
After technical rounds, Reliance usually closes with a short HR / hiring-manager conversation: motivation, location, notice period, and a couple of behavioural stories. Prepare those answers on the dedicated page rather than cramming them into this hub.
