Hey Tim! Hope your doing good
I was just wondering if I can do my Coding Interviews in Python itself?
Or do I need to do those Data Structures specifically in Java/C++?

I think I want to be Data Scientist/ Machine Learning Engineer, so I want to learn DS and A's in Python ( as there are asked for FAANG regardless of your position)
