- GeeksforGeeks: For conceptual understanding and coding examples.
- LeetCode: For practicing problem-solving skills.
Round 3: Final Interview
- Interviewer: Senior Developer
- Focus Areas: Problem-solving, coding skills, and analytical thinking.
Questions Asked:
- Database Design Question: A conceptual problem to test database knowledge.
- Math-Based Question: Calculate the new coordinates of a square after a transformation.
- Application Design Challenge: Discuss the challenges involved in developing a WhatsApp-like application within their system.
- Coding Task: Write a function to check if a specific file exists in a directory.
Provided Functions:
Task: Write a boolean find(String folder, String file) function to search for a file in the directory.
Solution Tip:
Use recursion or traversal techniques like BFS (Breadth-First Search) or DFS (Depth-First Search) to explore subdirectories systematically.
- I solved this problem using BFS, which allowed me to explore all subdirectories and files efficiently while keeping track of visited folders.
Outcome
I was thrilled to receive an offer from Zeus Learning for the Software Developer role!
