Data Structures and Algorithms Concepts Questions

Assesses familiarity with core computer science fundamentals needed to follow technical conversations and evaluate candidate fit for engineering roles. Topics include common data structures such as arrays, linked lists, stacks, queues, trees, heaps, hash tables, and graphs; algorithmic patterns for traversal, search, and sorting; and asymptotic time and space complexity analysis. Candidates should explain trade offs between approaches and why a particular data structure or algorithm is appropriate for a given problem.
