Had a brief interview/screening at a career fair at University. About a week later I was invited for 5 hours of interviews/lunch. After a brief introduction, I interviewed with 3 different people individually. All were nice and asked general questions about myself and about how I work. Some were more relaxed while others stuck to a standard interview format. Afterward, there was a data analysis/case study section where each candidate had to correct errors on spreadsheets and a powerpoint. Overall, a great experience.
