I applied online on the weekend and was offered an initial interview by the following Tuesday. I had the interview via phone two days later. During the interview, which lasted about half an hour, I spoke with a current project manager/implementation consultant. He was very pleasant and gave really useful descriptions of the position and training process (basically that at first you are in charge of installing a one specific software on one project and that you have plenty of support and supervision if desired. You also receive anywhere from 2-6 months training before starting the job full time). He also said that, despite the daunting 75% travel time listed in the job description, that the travel time really amounted to about four days a week, with every Friday being in the office (at least that was the case for him), and that he had all weekends in Madison, WI.
After that interview, I was asked to take an online skills assessment and a personality profile. The skills assessment was basically a miniature standardized test. They said you didn't need to study for it, and while that is true, if you haven't taken that sort of test in a while, it might be useful to brush up on general timed test-taking skills with mock intelligence tests, etc.
I was not asked to have a second round interview, but I found the entire interview process to be extremely efficient and amiable. You definitely are not left hanging for very long as to whether they want to pursue you in the interview process.
