Where do I even start, asked me everything about C++ under the sun, learn how to implement data structures in C and write all the .h and .c functions. Expect quant level interview questions with memory allocation in theory aswell.
Sigiloso
Making a linked list isn't hard but writing every function in C with a .h and .c with stacks and trees is horrible and im not too sure how someone is gonna do that without at least referencing some sort of docs.
