This was a Take Home test. I got a coding assignment where in I had to make a simple iOS app which can fetch data from an API and display it as a list on the screen. I used SwiftUI as its faster to code there. It was not complicated at all if you know youur stuff and they asked me to include tests (both Unit and UI). I already had my code snippets ready (for example for a Network class) so I could write a lot more code quite easily. It was taken on Hackerrank and I had 120mins to complete it. I read the instructions carefully and did as asked. I added comments to everything and made it extremely neat and structured using all the best coding practices of a large scale iOS project. Submitted it and that was it.

This was a discussion of my assignment. Take Home Follow Up. It was taken by an SDE 3 from US and he asked all sorts of questions about my code. I explained everything in great detail and told him what all things I would do better if i had more time. Simple round. Be ready to explain everything, every word and line.
