The question asks the candidate to implement a function that identifies which files from a source list need to be synchronized with a destination list.
This question is typically asked during the online assessment round for software engineering roles at Jump Trading. The interviewer is evaluating the candidate's coding skills, problem-solving abilities, and understanding of file synchronization concepts. A strong performance in this question demonstrates the candidate's ability to write efficient code and handle data structures effectively.
What the Interviewer Expects
- Clearly define the problem and requirements.
- Implement an efficient algorithm to compare the two lists.
- Handle edge cases, such as empty lists or duplicate filenames.
- Provide a time and space complexity analysis of the solution.
- Write clean, readable code with appropriate comments.
Key Topics to Cover
How to Approach This
- Clarify input constraints and edge cases before writing code.
- Walk through your approach verbally and confirm with the interviewer before coding.
- Start with a brute force solution, then optimize. Mention time and space complexity.
- Test your solution with examples, including edge cases like empty input or duplicates.
- Consider common patterns: sliding window, two pointers, hash map, BFS/DFS, dynamic programming.
Possible Follow-up Questions
- How would you modify your solution to handle large datasets?
- What if the source and destination files were stored in a database instead?
- Can you explain how your solution would change if you needed to synchronize file contents as well?

Requirements
To solve the problem, we need to identify files in the source_files list that are not present in the destination_files list. The output should be a list of filenames that require synchronization....
Approach
We can use a set to store the destination_files for efficient lookup. By iterating through the source_files, we can check if each file exists in the set of destination files. If it does not exist,...
