I applied through college or university.

Home test, 40 min for HackerRank/LeetCode style question. 60 min for debugging task of a repository of a full-stack app. One API call doesn't behave as expected and you need to fix the bug so all the tests are passing.

Amazon Online Assessment Coding Question – Circular Delivery Hubs

You are given a circular network of delivery hubs. The function has the following signature:

def computeMinDeliveryTime(deliverySequence, hubTransitionsTime):

• deliverySequence contains the hubs that must be visited, in the given order.
• hubTransitionsTime[i] represents the travel time between hub i and the next hub in the circular network. The last hub is connected back to the first hub.

For every pair of consecutive hubs in deliverySequence, the delivery agent may travel either clockwise or counter-clockwise around the circle. The travel time of a route is the sum of the transition times along that route. At each step, choose the direction that minimizes the travel time to the next required hub. Return the minimum total time required to visit all hubs in deliverySequence in order.

Example:

• deliverySequence = [1, 4, 2]
• hubTransitionsTime = [2, 4, 1, 3]

The agent starts at hub 1, travels to hub 4 using the shorter direction, and then travels from hub 4 to hub 2 using the shorter direction. The result is the sum of the minimum travel times for all consecutive pairs in deliverySequence.
