There was an automated simulation where I had 60min to complete set tasks. Followed by telephone interview with the hiring manager. Another stage was writing a document to answer the question that I was able to choose from the list of potential questions. Finally the loop that lasted 5 hours all together.

Long process. You get a couple initial phone screens. Then you're set up for 1/2 day of interviews. I had 3 or 4 over half a day. Make sure you take advantage of the resources they provide.
