Coding questions
Jio Online Assessment
Overview
Here is how public prep guides and student write-ups describe the Jio online assessment. This is not an official company brochure.
Reliance family hiring: Jio tech tracks sit alongside core RIL GET hiring processs with shared 3-round skeleton.
Usual selection rounds
Rounds students usually mention: Written / aptitude+technical (+coding in some Jio GET guides) → Technical interview → HR
| Item | From student reports |
|---|---|
| Platform | Written / online assessment |
| Online test summary | FACE Prep: written is first round then tech+HR. Some 2026 Jio GET guides describe a long aptitude+coding assessment window - treat as guide-specific and check your college placement email. |
| Eligibility notes | FACE Prep GET-style: ~60%/6.5 CGPA B.Tech, 60% 10th/12th, no active backlogs, ≤1 year education gap; some Jio GET guides cite ~6.75 CGPA - verify notification |
| Branches (reported) | CSE/IT/ECE for Jio Platforms; core branches for RIL Core |
Online test sections
| Section | Questions | Time | Notes |
|---|---|---|---|
| Aptitude / technical written | - | drive-specific (one guide cites a long combined window) | Your college placement email overrides |

Sample practice question styles
These are practice questions for speed - not claimed to be from a real Jio live paper.
Coding Q1: First unique character
Problem: Find the first non-repeating character in a string and return its index, or -1 if none exists.
Approach: Count frequencies in one pass (hash map or array of 26 for lowercase). Second pass returns the first index with count 1.
Complexity: O(n) time
Jio tip: Restate the problem, sketch a brute-force idea, then tighten it. Call out edge cases (empty input, single element, overflow) before you write code.
Coding Q2: Stack with min
Problem: Design a stack that supports push, pop, top, and getMin in average O(1) time.
Approach: Keep a parallel min-stack (or store pairs). When pushing, also push the new minimum. When popping, pop both stacks.
Complexity: O(1) per operation amortized
Jio tip: Restate the problem, sketch a brute-force idea, then tighten it. Call out edge cases (empty input, single element, overflow) before you write code.
Coding Q3: Maximum subarray sum (Kadane)
Problem: Given an integer array, find the contiguous subarray with the largest sum and return that sum. Example: [-2,1,-3,4,-1,2,1,-5,4] → 6 (from [4,-1,2,1]).
Approach: Keep a running sum. If the running sum drops below 0, reset it to 0 before taking the next element (or track the best ending-here value). Track the global maximum as you scan once from left to right.
Complexity: O(n) time, O(1) extra space
Jio tip: Restate the problem, sketch a brute-force idea, then tighten it. Call out edge cases (empty input, single element, overflow) before you write code.
Coding Q4: Reverse a string in place
Problem: Given a mutable character array representing a string, reverse it in place without allocating another array of the same size.
Approach: Use two pointers at the start and end. Swap characters, then move inward until the pointers meet. Watch empty and single-character inputs.
Complexity: O(n) time, O(1) extra space
Jio tip: Restate the problem, sketch a brute-force idea, then tighten it. Call out edge cases (empty input, single element, overflow) before you write code.
