MHP - A Porsche Company Java Intern Developer interview questions

It was 2 parts interview: an HR interview on the phone and an online technical review. The first part was a nice talk about the experience I had and the mission and goals of the company, while the technical interview was about Java and a lot of OOP problems, where they had prepared more than 20 questions with code and asked me questions like "What kind of output will return this function?" or "Why is this throwing an error?". Even if I hesitated or looked confused, they helped me to calm down and not get more nervous. I also responded wrong to one or 2 questions but they were very nice about it. The communication and their interviewing skills were very helpful. I would like to mention that it was during the pandemic so it might be a little different now.
