Today, let's dive into the most important topic in the coding interview series: 🚀 *Real-World Mock Interviews* This phase simulates real interview pressure to help you: ✅ Strengthen your problem-solving under time constraints ✅ Clearly structure and communicate your thoughts ✅ Practice writing clean, bug-free code ✅ Build confidence for actual interviews 🧠 *Key Areas You'll Be Tested On* 🔁 Core Topics Review - Arrays & Strings - Hashing & Recursion - Linked Lists, Stacks & Queues - Trees & Graphs (DFS, BFS) - Sorting & Searching - Dynamic Programming - Problem-Solving Patterns: → Two Pointers → Sliding Window → Binary Search 🗣️ *Interview Skills* - Asking clarifying questions - Explaining your thought process - Handling follow-ups & edge cases - Discussing time/space trade-offs - Debugging calmly under pressure 🛠️ *Sample Mock Interview Problem (Level: Medium)* *Problem:* Given a list of daily stock prices, write a function to find the *maximum profit* you can achieve by buying and selling once. *Example:* Input: `prices = [7,1,5,3,6,4]` Output: `5` Explanation: Buy at `1` and sell at `6`. 🔑 Optimal Python Solution ```python def max_profit(prices): min_price = float('inf') max_profit = 0 for price in prices: min_price = min(min_price, price) profit = price - min_price max_profit = max(max_profit, profit) return max_profit ``` *Time Complexity:* O(n) *Space Complexity:* O(1) *Note: Equivalent code can be written in C++, Java, JavaScript, etc.* 💬 Real Interview Tip Speak your thoughts out loud: “I’m iterating through the prices to find the minimum so far and calculating the potential profit at each step…” Interviewers value your *approach* and *clarity*, not just the final code. *React with ❤️ if you're ready for the interview questions* Coding Interview Prep Series: https://whatsapp.com/channel/0029VammZijATRSlLxywEC3X/753 Python Coding Challenge: https://whatsapp.com/channel/0029VaiM08SDuMRaGKd9Wv0L/1661
