Systems Installation Engineer Interview Sunnyvale, CA

You have two ropes. Each takes exactly 60 minutes to burn

 . They are made of different material so even though they take the same amount of time to burn, they burn at separate rates. In addition, each rope burns inconsistently. How do you measure out exactly 45 minutes?

Interviewer botched question delivery making it very confusing.

Burn rope A at both ends and one side of rope B. When A is all burnt up, lit other end of rope B, equals 45mins.
