This was an in-campus group project interview for recent graduates. It was a one whole day group project, where they give you their project architecture and a booklet that explains what your group needs to do. Accessing Google and asking for your group members help is allowed, but you are expected to be able to write your code and generate output using their code architecture. You would be called twice for a one-on-one during the day that mainly deals with the code and your logic/reasoning. Keep coding till then. You will not have to prepare anything about your work experience/skillset or about yourself.
