Tldr: hilariois scam website is hilarious

Today I saw a website that was obviously a scam, but it was quite hilarious: it said you could download an ebook and they tried to trick the user into clicking the fake download links. It was a textbook for engineering and at the botom of the page they had those fake user comments that encouraged people to du those things you are asked for after clicking the wrong download button (like entering your bank info). They described how their friends couldn't believe what an awesome book they got for free and so on and that they really loved reading it. Reading an engineering textbook. Also, and that made me lol quite hard: they discribed the condition of the book as "used with a few water marks". A fucking pdf with water marks...

I am just student looking for job, and got this pre interview test:
Develop an Android or iOS app with login and password input field, download button, place for image we prvided.

What we are looking for in the code ?
internal quality:
-consistent formatting of the source code
-clean, robust code without smells
-consistent abstractions and logical overall structure
-no cyclic dependencies
-code organized in meaningful layers
-low coupling and high cohesion
-descriptive and intention-revealing names of packages, classes, methods etc.
-single small functions that do one thing
-truly object-oriented design with proper encapsulation, sticking to DRY and SOLID principles, without procedural anti-patterns
-lots of bonus points for advanced techniques like design patterns, dependency injection, design by contract and especially unit (or even functional or integration) tests

external quality:
-the app should be fully functional, with every state, user input, boundary condition etc. taken care of (although this app is indeed very small, treat it as a part of big production-ready project)
-the app should correctly handle screen orientation changes, device resources and permissions, incoming calls, network connection issues, being pushed to the background, signing deal with the devil :D and other platform intricacies and should recover from these events gracefully
-lowest API level is not defined - use what you think is reasonable in these days
-bonus points if the app interacts with the user in an informative and helpful way
-bonus points for nice looks - use a clean, simple yet effective layout and design

... I mean really ? and they give me like 2 days ?

I want to create a condition on my webpage that only when a user is a YouTube subscriber he/she can make downloads.

Someone have any idea how i could do that? 🤔 I tried github and stack overflow but had no success

I looked on github, but had no success.
