Eaton Recursos Humanos interview questions

I sent my application, and a month later got spontaneous call from one of their recruitment team. The call was a 5-10 minute interview, it was formal but very brief. I was then sent an email inviting me to the assessment centre the following week. There were about 20 other interns at the day, and it ran from 9:00- 5:00, however half were sent home at lunchtime, and the rest were interviewed further. The day consisted of, 2 group tasks (both presentations) and an intray test, and a sort of IQ test. It was very exhausting but well structured. Sadly I didn't make it passed lunchtime, but we got feedback before we went home.
