First interview was a question about BST. The recruiter was very nice. In the second interview I don't remember the big question, but I solved it and it worked. I then got questions about what does the "new" keyword in C++ do exactly, or when typing "Object a = b" (where 'b' is another 'Object'), what actually happens (copy constructor?), and such questions; they were all pointed out from the code that I wrote, asking "what if we do this instead, what happens?" I didn't answer all of these questions correctly so I didn't pass for the third interview. However I was informed earlier that the third interview would've been directly after the second one and after that would be the final round of interviews.

Pretty good, not too complicated, was comfortable. Mostly LC questions, and was easy enough that you should be able to do it after doing NC150. good luck for the interview!
