Yes, I just basically gave you some of the questions that fked me up on the interview imo. I was self-taught in Python so although I had experience with things like multiple inheritance or knowing how to write classes and functions, since I had a github project on algo trade as well, I didn't know the terms and what they meant, which caused the lady to be hesitant when I asked her to elaborate more on it, as in instead of asking me "can you tell me what is multiple inheritance?" she can just ask me "have you ever tried to use a class as an argument/variable in another class, or objects, where you can use more than just the parent class? If so can you elaborate?" But now I know, so yea, study the academic terms if you're self-taught, other than that. Coding is fairly easy, just gotta be decent at math and basic coding.
