Tech Challenge - Frontend Mobile Developer
You have to build the front-end of a mobile app in React Native which does the
following.
User should be able to sign up. For signing up, user should be asked to enter
mobile, get an otp, enter the otp, verify it. If verification is correct, user
can enter her name and sign up as a user. OTP for this challenge can be 0000.
User should be able to sign in. For signing in, user should be asked to enter
mobile, get an otp, enter the otp, verify it. If verification is correct, user
is taken to the home screen which shows "Welcome " and the user name.
User should be able to log out.
There are 5 images. (<http://getdrawings.com/get-icon#one-icon-3.png>

<http://getdrawings.com/get-icon#serial-number-icon-18.png>
<http://getdrawings.com/get-icon#number-one-icon-17.png>).
The home screen shows the user these images one at a time. Each image has a
name which is the number contained in the image. So an image showing 1 has the
name "One", image showing 2 has the name "Two" and so on.
If the user swipes left, the image is rejected. User sees a message user name
+ ", you have rejected image " and then the rejected image's name.
If the user swipes right, the image is expressed interest in. The user should
see a message user name + ", you have selected image" and then the image's
name.
If the user doesn't do anything for 5 seconds, or when the user swipes as
above, she is taken to the next image. If we are already at the final image,
then the user should see upon expiry of 5 seconds or swiping, a message ", you
have rated all the images. Thank You!"
The app should retain the state i.e. if the app is closed and reopened, user
and image details should be retained.
Write tests!
Run it. Record a video of your screen in your voice running the app.
You don't need to make any API calls for it. Just work on the frontend.
