Dropbox Interview Questions & Answers

Q: Find duplicate files in a file system.

A: Group files by size first, then hash only the same-size candidates to confirm duplicates. That avoids hashing every file and keeps the work proportional to real collisions.

Answer by AI

Walk the tree and bucket files by size, since different sizes cannot be duplicates.
For each size bucket with more than one file, compute a content hash and group by hash.
Optionally verify hash matches with a byte comparison to rule out rare collisions.

Q: You have the value of a stock for the next n days. Given that you can only buy or sell at most 1 share each day, maximize your profit after n days.

A: With at most one share held and unlimited transactions, sum every positive day-to-day price increase. That captures the maximum profit greedily.

Answer by AI

Iterate through prices once, comparing each day to the previous day.
Add the difference to profit whenever today's price is higher than yesterday's.
Runs in O(n) time and O(1) space; each rise is captured as buy-low sell-high.

Q: Minimum Window Substring.

A: Use a sliding window with two pointers and a character-count map for the target. Expand to cover every needed character, then shrink from the left to find the smallest valid window.

Answer by AI

Build a frequency map of the target string's characters.
Expand the right pointer until the window contains every required character.
Shrink from the left while still valid, tracking the smallest window; O(n) time.

Q: Design Dropbox.

A: Cover file upload and download, chunking, metadata storage, sync across devices, and conflict handling. Walk through block storage, a metadata service, and notifications for real-time sync.

Answer by AI

Split files into chunks, deduplicate by chunk hash, and store blocks in object storage.
Keep a metadata service tracking file versions, chunks, and per-device sync state.
Use a notification service and client watchers so edits propagate and conflicts resolve predictably.
