Gudinace on Switch

I am a full stack developer with 2.5 years of experience currently working at a global MNV. My current skill set includes java, angular, spring boot framework.

I am planning for a switch. I read on the internet that to crack a MAANG or some company of that level you need to have a good understanding of Data Structures and Algorithms(DSA).

How to start with DSA preparation. I see there are a lot of resources. I feel overwhelmed by seeing all of them. Are there any good structured courses which teach DSA.
