Mobile System Design Exercise: File Downloader Library

Understanding the use case and business requirements is essential for designing a file downloader library that meets the specific needs of the application or system. Here are a few questions to help clarify the use case and gather business requirements: <ol> <li>What is the primary purpose of the file downloader library?</li> <li>What types of files will be downloaded using the library? (e.g., images, videos, documents)</li> <li>How will the library be integrated into the mobile application? Is it intended for a specific platform (Android, iOS, both)?</li> <li>Will the library support downloading files from remote servers or from local storage within the mobile device?</li> <li>What are the expected download volumes and file sizes? Is there a need to optimize performance for large files or high-volume downloads?</li> <li>Should the library support resumable downloads, allowing users to pause and resume downloads at a later time?</li> <li>Is there a requirement for concurrent or parallel downloads, allowing multiple files to be downloaded simultaneously?</li> <li>Are there any specific security requirements, such as encryption of downloaded files or authentication for accessing restricted resources?</li> <li>Should the library provide features for managing downloaded files, such as organizing them in folders, deleting files, or renaming files?</li> <li>Are there any specific performance or latency requirements for the file downloading process?</li> <li>Should the library provide any reporting or analytics capabilities related to file downloads?</li> <li>What are the expected target platforms and versions of the mobile application?</li> <li>Are there any regulatory or compliance requirements that need to be considered, such as data privacy or GDPR?</li> <li>What are the common file types and extensions that will be downloaded using the library? (e.g., PNG, PDF, MP4, DOCX)</li> <li>Are there any specific file types or extensions that require special treatment or processing during the download?</li> <li>Should the library have built-in support for handling specific file types, such as image compression, video transcoding, or document parsing?</li> <li>Are there any restrictions or limitations on the file types or extensions that can be downloaded using the library?</li> <li>Should the library provide functionality to handle different file versions or variations, such as different encoding formats or compressed files?</li> </ol> When discussing system design in an interview, it is important to prioritize the requirements and focus on areas that showcase your strengths and expertise. While it is impossible to cover every requirement comprehensively within a limited time frame of 45 to 60 minutes, you can guide the conversation by asking the interviewer which aspect they would like you to delve into first. By doing so, you can strategically steer the discussion towards topics where you feel most confident and have relevant experience. A successful interview is not just about directly answering the interviewer’s questions; it also involves highlighting your strengths and conveying your knowledge on the specific areas you have expertise in. <a href="https://levelup.gitconnected.com/mobile-system-design-exercise-file-downloader-library-a0e9574218ca">Visit Now</a>
