Fill 5 gallon, pour it into 3 gallon. Dump the 3 gallon. pour the 2 gallon remaining in the 5 gallon bucket into the 3 gallon bucket. Fill the 5 gallon bucket, fill up the rest of the the 3 gallon bucket. You have 4 gallon in the 5 gallon bucket

The interviewer specifies that there are no fill lines, and the measurement has to be exact (i.e. no guessing the halfway point of each bucket.

fill each bucket exactly halfway.

additionally, twist the question into a simple solution. 'if the 5 gallon bucket has fill lines, simply fill it to the 4 gallon mark'.

1. Fill 5 gallon bucket completely. 2. Place 3 gallon bucket into full 5gallon bucket to displace water, leaving 2 gallons. 3. Pour 2 gallons into 3 gallon bucket. Repeat 1 more time.
