There were a total of three phone interviews: HR and two planning managers. The interviews weren't difficult, but it was a really long day and I had a hard time keeping track of all the different people who interviewed me. The day started with a (timed) assessment test (math, logic, personality questions). After the test I was on a tight schedule for interviews. One of the early interviewers ran late and that threw off the whole schedule. I didn't get to have lunch and some of the interviewers had to double up with me. After a few hours of answering the same questions over and over I was tired and hungry and just wanted to leave. I think this really started to show towards the end of the day. Of all the people I met, no one could tell who I would be working for (which I didn't like). Everyone I met was nice.
