Round 1 Coding Design Implement a simplified JSON parser capable of parsing custom-formatted log files or handling strings containing escape characters. The problem itself wasn't difficult. During the interview, I wrote it in Java. Some boundary conditions and special rules needed to be considered, making it somewhat complicated. The interview focused more on communication with the interviewer. Overall, the difficulty level was medium.
Round 2 Algorithm: Array Range Problem Given a non-overlapping array of ranges and an index, delete the range at that index and return the remaining ranges. This was the original problem. After I finished, the interviewer asked two follow-up questions:
Follow-up: If the range array is very large and deletion operations are frequent, how would you design a data structure to optimize the efficiency of deletion operations? If the requirement is to support dynamic insertion and deletion of ranges while always maintaining non-overlapping ranges, how would you implement this? image.png (142 KB, Downloads: 0) Download Attachment Save to Album image.png Uploaded 2025-09-28 13:15 image.png (133.12 KB, Downloads: 0) Download Attachment Save to Album image.png Uploaded 2025-09-28 13:15
