Explain Core CS and Database Concepts
Core Computer Science and Database Concepts
This interview focuses on fundamental computer science and database concepts. Be prepared to discuss and explain the following topics:
- Data Structures: Explain common data structures such as arrays, linked lists, hash tables, heaps, and trees, including when and why you would choose one over another for specific use cases.
- Algorithm Analysis: Compare the time and space complexity of sorting algorithms like merge sort and quicksort, and search algorithms like binary search.
- Multithreading: Define multithreading, describe common problems that arise when threads share state, and discuss potential solutions.
- Deadlock: Explain what a deadlock is, identify the conditions that cause it, and outline strategies for its prevention.
- Big Data: Provide a practical definition of "big data" and discuss its implications.
- Relational Database Keys: Define primary keys and foreign keys in the context of relational databases and explain their purpose.
