Interview Process
The interview process consisted of three technical interview rounds and one system design round. The questions were primarily high-frequency ones selected from a question bank.
Technical Questions
- LC 56: Interval merging or insertion of intervals, focusing on sorting and boundary judgment. Consideration of complete overlap and partial overlap cases was required.
- LC 347: Heap or bucket sorting to demonstrate understanding of data structures. Implemented using Python’s
heapq, with discussions on optimal complexity. - LC 3: Sliding window technique. The interview emphasized optimizing brute force solutions to O(n). Candidates were advised to draw examples to understand window movement and to pay attention to boundary conditions.
Tips & Insights
- Draw small examples before coding to visualize the problem.
- Be mindful of edge cases, such as empty strings or all repeated characters.
