The interview process is detailed on their website. After taking the online assessments, I was invited to an initial interview and took an in-person test (very similar to their practice test). After successful completion of the initial interview, I got an invitation to come to the site for more interviews and to get to know the company on a more personal level. In fact, there was really only one formal interview and the rest were pretty much conversations to get to know you better and vice versa. Overall, a great experience that proves the company wants to hire you for who you are, not necessarily just your specs on your resume.
