It was a long process starting with a phone interview which seemed to be just telling me about the job and making sure I was not socially awkward. I was notified a few days later that the next step in the process was a skills assessment which took a couple of hours and was mostly problem-solving, math questions, and riddles. A few days later I was invited for an on-site interview where I spent from 8:30AM to 4:00PM answering questions, sometimes the same questions to different people, and participating in situational analysis, etc. I was also required to have a presentation prepared. My presentation included diagrams and a model and some writing on the board. They will ask you and are looking for people who are willing to travel and have a solid work ethic.
