Work-at-home Challenge for Blue Bottle Coffee Engineering Manager
View BBCEngManagerChallenge.md

Engineering Manager Challenge (Allot at least 2 hours)

Note: Don’t feel constrained by the time limits.

Consider the following scenario:

You have 2 scheduled roasts of Hayes Valley Espresso totaling 50lbs. (For simplicity, assume that all batches are maximum of 30lbs for physical reasons).

Roast A, 20lbs available. 
Roast B, 30lbs available.
