When to Stop Learning Spring boot

So, I have been Learning Spring boot (at a very slow pace) for a while . i have covered things like Creating rest api, adding basic authentication, manipulating one controller with another, basic testing ,adding different roles, logging ,calling external APIs, query and criteria and some best practices like sonarqube.

I have been following a playlist but i am in a doubt that do i need to cover everything that spring boot offers like what other major things i need to learn, i am 2024 graduate and looking for a job so i don't have much time to cover everything.i have done internships in web development but not majorly in java domain .

The playlist i was following have just few topics remains like jwt authentication, integration of redis with spring boot and kafka and deployment of app on heroku.

So i need some guidance from you all guys like what more things do i need to cover that are essential for interview or the things that i have done are enough. Pls guide me. Also do tell what other things (technologies or topics ) do i need to prepare beyond springboot for interview.

Your guidance will save me so much time. Pls help!
