How long does it take to learn Angular so that you are ready to apply for a job?

I would say that, for beginners with some experience with JavaScript, it could take a month or two (even three) to wrap they head around the Angular framework and feel comfortable with it.

The tutorial (angular.io/tutorial) it's a good starting place and helped me to introduce other junior devs to Angular, and the process of building a web app from scratch.

I would suggest to follow the tutorial and build an app of your liking - that really helps in the learning journey and keeps you focused and challenged.
