CPU cores on the device."Candidate: "On the other hand - each downloader would be blocked on the network I/O so we can use a higher number like 16."Candidate: "It's hard to figure this out for the general case. So 4-16 seems reasonable by default. The user may pick a better size depending on the use-case."Candidate: "Should we support progress reporting for active downloads?"Interviewer: "Might skip it for now and discuss it if we have time"Candidate: "Do we need to handle authentication?"Interviewer: "Let's skip it."Candidate: "Do we need to support HTTP ranges for resumable downloads?"Interviewer: "We can leave it out of scope"Platform Specific Considerations:iOS:Background Download Considerations: Ask about background download requirements early. iOS has strict limitations on background tasks. Using URLSessionConfiguration.background(withIdentifier:) allows downloads to continue even when the app is suspended, but it comes with limitations (e.g., the system decides when the download occurs). Consider the implications of using BackgroundTasks.framework for scheduled background tasks.File System Access: Understand iOS's sandboxed file system. Know the common directories (Documents, Library/Caches, tmp) and their appropriate uses.Android:Background Download Considerations: Android's background execution limitations have evolved. Consider using WorkManager for background tasks. WorkManager is a more general-purpose solution for deferrable, guaranteed execution tasks.DownloadManager: While Android's DownloadManager is an option for background downloads, its usage is often discouraged due to potential security concerns and limited control over the download process. It can be prone to vulnerabilities related to file path injection and unintentional overwriting of existing files. Consider carefully whether the benefits outweigh the risks before using it.Permissions: Android requires explicit permissions for accessing external storage. Ensure the design accounts for requesting and handling these permissions (READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE for older Android versions; scoped storage considerations for newer versions).Power Management: Android has aggressive power-saving features (Doze mode, App Standby Buckets). Understand how these might impact background downloads and consider
