My first interview was a phone interview, very straightforward about my resume. My second interview consisted in 7 1:1 interviews of 30 mins each with 7 different departments. It felt long because I did not have a break. They started by giving an overview of their department and then they asked me about my resume. They also asked me questions like what was the most difficult obstacle you overcome and where do you see yourself in 5 years. After that interview, I was asked to go back to interview with two of the departments. The format was basically the same except they asked me specific questions about Excel.
