3 Rounds
1. Basic Coding round - Interviewer will ask simple DSA questions, python, Django preffered.
2. DSA/MC round - Complex coding questions - stack, heap
3. System Design round - will ask about your current project, system design and machine code might be asked.
Interview questions [1]
Question 1
Reverse string with stack in python
Django lifecycle
I applied online. I interviewed at Innovaccer in Feb 2026

Key Concepts
DFS / BFS
Mirror comparison
Tree recursion
Queue-based traversal
2️⃣ Count Subarrays With All Distinct Elements
Problem
Given an array, count the number of subarrays whose number of distinct elements is equal to the total number of unique elements in the entire array.
Key Concepts
