The role was "PHP Developer (m/f/x) / Berlin or remote". But my interview was "Senior PHP Developer". It does not matter, I am a "Senior PHP Developer". There was lots OOP questions. I answered all, but towards the end of the interview, the questions evolved towards filtering get post data. "The best" is user object question. A question has come to the screen, every side is very very bed code. They ask where the problem is. I said that everywhere of this code smells. $user->name.' '.$user->surname. etc. We have to use $user->getName() better or using magic __get would be better for this situation. One of refuse reason is "injecting the user object". My answer is an explanation of "injecting the user object". Interviews are some smelling.
