Interview preparation journey
Journey
My interview preparation started with revising core concepts in programming, data structures, algorithms, and databases. I practiced frontend and backend technologies by building small projects to strengthen my practical understanding. I regularly solved coding problems on platforms like LeetCode to improve problem-solving and time management skills. I also reviewed system design basics, RESTful APIs, and project architecture to prepare for technical rounds. Mock interviews and mentorship sessions helped me practice articulating my experience and approach clearly, making me confident for real interviews.

Coding problem3
1. Build a Simple Stopwatch in JavaScript
Create a stopwatch that displays elapsed time in seconds. Implement functionality to start, stop, and reset the timer. The stopwatch should update the display every second and accurately track the elapsed time from when it was started.
2. Build a Tic-Tac-Toe Game
Build a Tic-Tac-Toe game in a React application where two players take turns marking "X" and "O". Implement logic to:
- Alternate turns correctly between players.
- Check for a win condition when a player aligns their symbols in a row, column, or diagonal.
- Declare the winner when a win condition is met.
Problem approach
I implemented the game logic in React by alternating turns between "X" and "O" after each move. I updated the board state on every click and checked for a win condition after each turn by verifying rows, columns, and diagonals. If a player met the win condition, the game declared them as the winner. I also made sure players couldn’t overwrite already filled cells, ensuring the game ran smoothly in all scenarios.
3. React Form to Display Submitted Data in a Table
Create a form in a React application where users can input data (e.g., name, email, age). Upon submission, the entered data should be added to a table displayed below the form. The table should dynamically update with each new submission.
Problem approach
I built a form in React with an onSubmit handler function. The function executed correctly, and upon submission, the entered data was dynamically displayed in a table format below the form.
