INSTRUCTIONS TO CANDIDATES

ANSWER ALL QUESTIONS

You will be assessed on your ability to complete all the below features. You will not be judged on how beautiful you can make your UI, but please try to use layout margins/padding to space your views appropriately, and specify text sizes to make things more readable, where necessary. The documentation for the REST API that should be used for these tasks is included at the end of this document.

1. A login screen

○ Customer Service agents provide a username and password and tap a button to submit.

○ If the provided credentials are rejected by the server, then an error should be displayed.

○ If valid credentials are provided, then the app should advance to the next screen, and use the auth token in the response for all subsequent requests.

○ Your username will be your email address, and your password should be your email address in reverse. Please make sure to use a real email address that you own for this exercise.

2. A screen that displays all message threads

○ Display a list of message threads, where each customer’s messages should be treated as a separate private thread.

○ The latest message of each thread should be surfaced in this list. At a minimum, please display the message body, timestamp, and agent OR user id (whichever of these is relevant) of the sender.

○ If any of the message threads in the list is tapped upon, then the app should advance to the next screen.

3. A conversation screen to view an individual message thread and respond

 ○ A sorted list of all messages (both customer and agent) relevant to the thread should be displayed here.

○ The agent should be able to respond to the customer using an input field.

○ At a minimum, please display the message body, timestamp, and agent OR user id (whichever of these is relevant) of the sender.
