Three interviews: one over the phone and two in person. The phone interview is relatively basic, just an overview of your resume and interest in the position. The first interview is almost a repeat of the phone interview but it dives deeper into you resume in regards to how your work experience qualifies you for the job. The last interview is a little more intense. It's used to see if you would be a good fit for the position and definitely seeks to determine how passionate you are about the field.
