I applied online. I interviewed at Caldera (Burnsville, MN) in Nov 2014
Interview
Usually takes 1-2 interviews. Normally very quick if they want you. Should only be about 30 min to 1 hour long. Depending on the applicant, you will have to talk to at least 2 people. Afterward you will have a skype interview with one of the top level executives.

Interview
The best part was they had me fill out a form online with all kinds of information about my interests and past experiences in life and work. They wanted to know about me and my pets and my family and my food interests. They eventually got to the technical meat of the interview but I found them empathetic.
