Coding interviews aren't just about writing code; they are about choosing the right tool for the job. Do you use a Stack or a Queue? Is a Hash Map better here than a Tree? The **DSA Quiz** tests your conceptual clarity. Before you open LeetCode, use this tool to ensure you understand the theoretical underpinnings of Data Structures and Algorithms. It's the perfect warm-up for your interview.
Select a data structure (e.g., Arrays, Linked Lists) or Algorithm (e.g., Sorting).
Attempt 10 multiple-choice questions selected for interview relevance.
Read detailed explanations for incorrect answers to understand the "Why".
Move from Easy to Medium questions as you improve.
Questions are curated from actual interview experiences at top tech companies. **Conceptual**: "What involves the least time complexity for search?" **Practical**: "Predict the output of this recursive function."
**Speed**: Learn to identify patterns like "Sliding Window" or "Two Pointers" instantly. **Theory Check**: Verify if you truly understand Big-O notation and Space Complexity. **Interview Simulation**: The pressure of a timer mimics the real online assessment environment.
**Pre-Interview Warmup**: Doing a quick 5-minute quiz before a technical round. **Revision**: Quickly brushing up on Graph algorithms before a test.
Client-side logic with a randomized question bank to ensure variety.
Focus on Time Complexity (Big O). It is asked in every single interview.
Draw diagrams on pen and paper for Linked List and Tree questions.
Don't guess. If you don't know, mark it for review.
