A local candidate can choose to onsite 2 rounds instead of 2 phone screens.

Onsite 1:
- Find max horizon of an image. A horizon is a path from left to right (right, upper diagonal, lower diagonal) with value of min cell on the path. (DP)
- Allocate and release IDs. (queue, bitarray, segment tree)

Onsite 2:
- Behavior questions
- Find duplicate files
- Web crawler (multi-threading and locking mechanisms) (system design)
- Design Dropbox file sync feature (system design)





补充内容 (2017-7-2 04:56):
A number of a path can go to next column by left to right, left to upper diagonal, or left to lower diagonal (choose the min value as path). However, we want to find the max of all possible paths.
