ETS interview questions

I submitted by CV through a contact and was invited for an all-day interview. There was one hour with HR, one hour with the group director, one hour with potential colleagues, one hour with the whole group where I also had the chance to get some insights into a regular work day, work-life balance, etc., 1/2 hour group lunch with the whole department to check social skills during lunch, and most importantly there was one hour where I had to take a test, revise multiple-choice items and then talk about them with potential future colleagues.
