S4 Integration Software Developer interview questions

Met with lady from HR in boardroom and was presented with a code analysis quiz code snippet, where all the flaws/faults needed to be found within about 15min. Thereafter, I was introduced to what seemed to be one of the lead developers and head of development. They asked a couple questions regarding my answers on the quiz like "What was my favorite subject in uni?" "What sort of projects have you worked on?" "Why are you interested in becoming a part of S4?" etc etc. They also asked a couple of basic knowledge coding questions like, what is an array, what is the difference between a for loop and a while loop. What is a class? Stuff like that. Nothing hectic.

They will ask you about your cv. Problems you have faced and how you overcame them. Give you a code to look at, the code will have small errors and you'll need to modify it so that it can run better. They'll bring up everything on OOP
