I received a 15 minutes phone interview. Once you successfully pass this step, you will be invited in for a face to face interview. They called me a couple of days later for the interview, and it consisted of a panel of 3 managers asking different questions, some are situational, others are about your experiences, and what you will bring to the company. You must be very precise about your answers, also they want you to ask them questions as well. My interview was a little over an hour and questioning and asking questions as well. After the interview I got a call about 3 days later offering me the position. It's a long process with background checks and drug testing, but they were very efficient.
