Qualcomm Entry Level SWE Interview Experience

I recently completed a 6-round interview process, and I wanted to share my experience with the LeetCode community!

Each round tested different aspects of my problem-solving, system design, and behavioral skills.

Round 1: Coding Challenge LeetCode Question: Number of Islands Discussed edge cases and optimized the solution.

Round 2: Coding Challenge Problem: Password Generator Implemented a secure password generator with constraints like length, character types, and randomness.

Round 3: Frontend System Design Task: Design a 5-star rating React component Implemented a reusable and accessible rating component with interactive states and animations.

Round 4: Algorithmic Challenge LeetCode Question: "Assume that we already have a function that checks if a sentence is valid. Generate all valid sentences with the given set of words." Used Backtracking + Dynamic Programming to generate valid sentence combinations efficiently.

Round 5: API + Data Processing Task: Given a public API that provides recent match details, generate: A simple match report summarizing the results Player statistics, including performance metrics

Round 6: Behavioral + Graph-Based Coding Question Behavioral Questions:

How do you deal with a strict manager?

How do you handle strict deadlines and unclear instructions?

LeetCode Question: "Given a failing job in a dependency graph, list all the jobs that will fail." Used Topological Sorting / DFS to determine all impacted jobs.
