Your methods are good practices that every beginner developer should know and build upon. I am also a self taught FE developer with 6+ years experience and I used many of your tactics in interviews along the way. In fact, just coming from an interview where I used some of them and it went great :) In this fast paced and constantly changing branch, versatility is an important ability, as it's almost impossible to master all concepts/technologies required in a project. If you say that your mindset is oriented towards constantly learning new things and adapting to challenges, it will give you a big advantage in interviews. Make this look like one of your strenghts and it will get you a long way.
Best of luck Julia, and thank you for the article. Congratulations on your job, you're going to be a great developer !
