Coding Interview - The Task

You need to implement the following user story:

As a user, I want to see the trains that fit my travel schedule, So that I can decide what to buy

Spec

• Create an HTTP endpoint that will take one input: time in ISO 8601 format, e.g. 2011-12-03T10:15:30+01:00
• The API should return the next 3 trains from the time provided
• Schedules can be retrieved from the following two endpoints (we need them both):
  • https://60b8cf3cb54b0a0017c047bd.mockapi.io/s1
  • https://60b8cf3cb54b0a0017c047bd.mockapi.io/s2
• The time zone of the schedule is in UTC
• The schedule loops around, i.e. if my input is close to midnight, it should include results from after midnight
• We would like you to not use a database, but store data in memory

Start

• Clone the API: https://github.com/dscottie/simple_api
• Verify the /status endpoint

Bonus

• Change the S1 endpoint to the following (less reliable):
  • https://mercury-trains.herokuapp.com/s1x
• Can we paralelise the HTTP requests?
