Round 1: Technical Coding (DSA-focused)
The interviewer asked me a coding problem commonly known as the "Two Sum" problem.
I was given:
An array of integers
A target value
Problem:
"Return the indices or values of two numbers from the array that add up to the target."
I discussed both brute-force and optimized approaches:
Brute-force: Nested loops with O(n²) time
Optimized: Using a HashMap for O(n) time
I wrote clean, working code and explained edge cases as well.
Round 2: Product-Based Case Study
The second part involved a real-world app case study.
I was presented with a problem scenario and asked:
"How would you design a feature in a utility-based mobile application?"
They were looking for:
My thought process
Feature planning
UI considerations
State management
Offline sync / caching
API integration strategy
I walked them through:
Choosing the right architecture (MVVM)
Using Flutter widgets efficiently
Preferred state management (Provider or Riverpod)
Handling API data and exceptions
Ensuring user-friendly error messages and retry logic
Overall Feedback:
They were evaluating:
Problem-solving skills
Code optimization
App architecture understanding
Real-world product thinking
The discussion was collaborative and practical, aligned with their domain of utility and field workforce applications.
