## Overview & Hiring Pattern
Data Structures & Algorithms verbal interviews check if you can dry-run code out loud, choose the correct data structure, and explain the space and time complexity tradeoffs. The session tests your approach, not just typing code silently.

## What Sophia AI Evaluates in This Track
- Covers arrays, strings, linked lists, trees, graphs, hashmaps, and heaps
- Sophia tests time & space complexity — explain Big-O of your approach out loud
- Dynamic programming, backtracking, and divide & conquer strategy questions
- Configurable difficulty: Easy (TCS/Infosys) to Hard (FAANG-level)

## Frequently Asked Questions
### Q: How is a DSA mock interview different from solving LeetCode problems?
**A:** On LeetCode you code silently. In a real interview (and with Sophia), you must explain your thought process out loud, justify your approach, and discuss time/space complexity — all while someone is listening. Sophia specifically trains this verbal communication.

### Q: What DSA topics does Sophia focus on most?
**A:** The most frequently asked topics are: Arrays, Strings, Binary Search, Sliding Window, Trees (BFS/DFS), Graphs, Dynamic Programming, and Recursion. Sophia covers all of these with adaptive follow-up questions.

### Q: What difficulty level should I select as a fresher?
**A:** Set your years of experience to 0–1 and Sophia will ask easy to medium difficulty questions covering arrays, strings, linked lists, and basic sorting — typical of TCS NQT, Infosys, or Wipro fresher rounds.
