I was contacted for a phone interview within a week of applying. The phone interview is where they ask the basic interview questions - learning your experience and background. The day after the phone interview, I was contacted for the official/final interview. For the final interview, I was given a dataset and 4 questions to "answer" in a 30 minute presentation (the final interview). I was told they just wanted to see my analytical process and how my brain works. Then, after the presentation, they might ask some questions about your thoughts on the dataset or what you would do in a certain situation.
