A three-round interview process will thoroughly test your knowledge of core data structures. For each topic (stack, heap, linked list, tree, graph), expect questions on:
Implementation: Can you code a stack using a linked list?
Traversal: Perform iterative in-order tree traversal.
Application: Use a heap to find the top K frequent elements.
Problem-Solving: Detect a cycle in a linked list or a graph.
I applied through a recruiter. The process took 1+ week. I interviewed at OYO (Gurgaon, Haryana) in Dec 2020
