Design questions candidates report

File-sharing app with followers (machine coding)

How to design a cloud file storage and sync service like Google Drive or Dropbox: requirements, storage and traffic math, splitting files into content-addressed blocks, resumable uploads and deduplication, separating metadata from blobs, a change journal with cursors so every device syncs, push notifications, conflict handling and version history, sharing permissions, and the trade-offs.
Full walkthrough: Google Drive Practise on the design board
Notification service

How to design a shared notification service that any team can call: one API for push, SMS, email and in-app, user preferences and quiet hours, templates, separate priority queues so a marketing blast never delays a login code, per-provider rate limits, retries with backoff, deduplication, dead device tokens, bulk campaign fan-out and delivery tracking.
Full walkthrough: Notification system
Distributed job scheduler

How to design a shared scheduler that runs millions of one-off and cron jobs on time: a jobs table indexed by next run time, partitioned schedulers that claim due work with leases, a unique run key so each tick fires once, a queue and worker pool with heartbeats, retries, timeouts and fencing tokens, and the midnight thundering herd, priorities and per-team quotas.
