I only made it to the tech screen. As others mentioned, it consists of multiple parts, and I only completed two.

Both were fairly straightforward if you were doing them in your own time. However, I tripped myself up trying to think too far ahead, coding for changing requirements, which slowed me down.

Below are the two questions I completed. You could probably feed them into ChatGPT and ask it to provide examples of more challenging third and fourth-level questions building off those previous to help you practice.

Given an input string: "UK:US:FedEx:4,UK:FR:Jet1:2,US:UK:RyanAir:8,CA:UK:CanadaAir:8"

This string represents flights between destinations in the format: "Source:Destination:Airline,...".

Write a function that takes a Source and Destination and outputs the cost.

(Building from the first question) Write a function that takes an Input String, Source, and Destination where there is no direct connecting flight. Output a route to reach the destination. The output should be in the format: return {'route': 'US -> UK -> FR', 'method': 'RyanAir -> Jet1', 'cost': 10}
