Does we have courses about OOP or Data structures and algorithms?

Hello everyone, I’ve been studying at for 3 months now, everything is great and I feel like my level is improving every day. And recently I interviewed at several companies to get a job as an intern. That’s when I realized I needed more knowledge about OOP or data structures and algorithms. There are also those things in’s courses, but it seems they don’t exist as a complete course yet. So I would be very grateful if a friend could introduce me to such courses, or share how you learned the above knowledge. Thanks a lot !
