At first, I received a call from Trish (HR I think), she was very nice and described the position details breifly and asked me a few questions to make sure it is the right fit for me.
Then, I met with Marc, the Hiring Manager. He was very informative, explained about the opportunity in a lot of details and answered all of the questions I had.
The third interview is the most important. The Manager has described the day to day of the position and the growth opportunities available. In addition, the compensation structure and the goals were broken down during this interview
