Find A Player Test Project

findap_test.md

Overview

One of the desired features for Find A Player app is a Contacts Sync service. You would need to implement one in Elixir using standard library, OTP and couple external libraries:

• Ecto
• Oban (optional)

When user allows phone contacts access mobile app makes a POST request to API server with the following structure:

"contacts": [
  {
    "name": <string>
    "importance_score": null | <positive int>
    "phone_numbers": [
      {
        "phone_number": <string>
      },
    ...
    ]
  },
  ...
]

After authentication step, we would get: current_user making request and the above payload ^

Consider the following user and phones structure in database:

Users

id
int

UsersPhoneNumbers

phone_number	user_id
unique string	fk to the users table

Task

Come up with database table(s) to interlink users phone number with contacts, process to import contacts in a reliable way, notifying client if there are any errors in the process.

(Optional) Notify client about progress, a simple message (via phoenix pubsub topic) would suffice.
