How interviewers test Data Structures
Real questions from Skilture's interview banks, with what the interviewer is listening for.
Software Engineer · intermediate
How would you decide between using a hash map and a balanced binary search tree for a given problem?
Listen for: A strong answer weighs constant-time average lookups against ordered traversal and worst-case guarantees. Red flags are naming structures without connecting them to access patterns, ordering needs, or memory trade-offs.
Software Engineer · basic
Explain the difference between an array and a linked list, and when you would prefer each.
Listen for: Look for contiguous memory and O(1) indexing versus cheap insertions/deletions and no random access. A weak answer recites definitions without a concrete situation where one clearly wins.
