The standard, 'why Amazon' Question
The maths question was based around picking packing and shipping, with packing broken down into mixed packages (consisting of 2 or more items) or single packages (one item). You were given the total output of mixed packages for the 10 hour shift (40,880) and told that this consisted of 70% or total packing. This mean that single packages were 30%. Obviously picking and packing are both 100% as everything that is picked is considered shipped on the same day. Using the pick rate (units per hour) you could break down how 102 employees would be split into the 4 functions over the shift.
When going through the maths in the interview, the interviewer changed the problem slightly and said that all single packages had to be shipped in the first half of the shift (5 hours). Obviously for this, total output does not change, but workers on single packages for the first 5 hours at least needs to double. This means that for the first 5 hours the number of workers on shift in mixed is reduced, however output is simply not just halved as workers are available foe mixed packing for the second half of the shift, while no single packages are required to be packed.
