ADP Innovation Labs Pre-Interview Assignment

Hello potential future coworker! :D

We're looking forward to having some great days working on creating new projects, debugging issues, planning applications, solving problems, and all of the other fun things we do here in Innovation Labs - together with you!

But before that, let's see if you can demonstrate some stock skills you'll need to be successful in this position :)

If anything isn't specifically called out here, feel free to be as inventive as you like - no pressure to adhere to any strict rules. Our primary goal is to know that you generally understand web application principles.

Have fun!

Task

Create a simple JavaScript (nodejs) application that makes an HTTP GET request to

https://interview.adpeai.com/api/v2/get-task

This endpoint will provide you with an id and an array of transactions data.

{
  "id":"81728ed3-25ff-473c-9491-4a2026dadd8c",
  "transactions": [
    // This will be an array of transactions
  ]
}

Each transaction object within the array has the following shape (details may be different):

  
{
  "transactionID": "TX_691",
  "timeStamp": "2021-05-25T17:35:19.460Z",
  "amount": 1060,
  "type": "alpha",
  "location": {
    "name": "New York, New York",
    "id": "L027145"
  },
  "employee": {
    "name": "Abram W Choi",
    "id": "SED133",
    "categoryCode": "red"
  }
}

With this data:

1. Get all the transactions of last year's top earner. This means find the employee with the highest sum total of amount within the prior calendar year. Prior calendar year means, if it is currently 2022, we want only to consider transactions in 2021.
2. With last year's top earner's transactions get the transactionIDs where the type is alpha.

Once you have an id and an array of transactionIDs (should be an array of strings), make an HTTP POST request to

https://interview.adpeai.com/api/v2/submit-task

with a JSON POST body including the properties id and result.

Body example:

{
  "id": "81728ed3-25ff-473c-9491-4a2026dadd8c",
  "result": ["TX_002", "TX_003"]
}

The submit-task endpoint will return as follows:

If you get 200, you are done!
