If you're just starting out, and I'm looking to hire you, I'm looking for samples of your work. Contribute to open source projects and build your own projects. They don't have to be rocket science. Just show that you have a handle on the Software Development Life Cycle, that you can work with and contribute to teams of people, and try to incorporate all the professional software development practices into your project. After you do that with a "Hello World" app, you can show off your coding skills more, but a very simple example will do to start.
You can also research a particular company's interview process and check their Glassdoor interview reviews. Here's some links to prepare for an Amazon interview: https://www.youtube.com/watch?v=vMQOg9C2R08&list=PLaViNjvnjP... https://www.youtube.com/watch?v=OB5noyXEv1o&list=PLaViNjvnjP... https://www.youtube.com/watch?v=RzlUQCy84rQ&list=PLaViNjvnjP... https://dev.to/educative/top-10-object-oriented-design-inter...
