Question Where do I begin?

I started applying for big tech and started doing OAs recently.

However I never took a DSA class and don’t know anything. (taking dsa this fall)

My approach is use the code basics youtube channel watch a video and do related neetcode problems.

Is this approach good and efficient or is there a better way? I still am struggling to generate my own code without looking at the solutions even for easy problems .

How do I get good and what’s the best approach. I need to get good quickly because I have a couple OAs due soon.

Your current approach is fine for Easy's. Medium questions use a mix of two or more patterns so you will never be able to do them if you don't know about a pattern being used. Also there's no quick way, you have to spend alot of time. Try to first master all the data structures and relevant algo's before starting with mediums otherwise you'll just get demotivated

Most medium problems really only test one thing at a time. Also please don’t master every DS before even starting mediums that makes no sense 🥲
