It was three total interviews. I started with a mutual contact for an informal conversation. He forwarded me on to HR who I had a 30 min interview with followed by a hour long panel made up of several current employees. Shortly after that, I spoke again to HR and they told me the interviews had gone well.

I had a 20-30 min phone interview. First, I gave a brief bio, then I answered questions about my completed coursework. He then went on to ask what my areas of interests are, and I had the opportunity to ask questions at the end. Next steps included going into the office and giving a technical presentation to a group panel.

Had a brief 30 minute phone interview. Got an on-site interview and spoke to three other senior analysts. Very informal and nothing too technically challenging. Gave a power point presentation on a topic of my choice. They said they'd get back to me in 1-2 weeks and its been 3 months. Unprofessional in my opinion.
