I had a phone interview first. After that I was asked to come for an on site interview.The in person interview was with 4 people, process took around 3 hours. I sat with one person as they showed me the position. The first three people I dealt with were polite and informative, I appreciated that greatly. A senior HR rep was the last person to interview me, he was fairly rude and accusatory in nature regarding my salary and desire to work at Biotelemetry (Even though I elected to do an interview for three hours). The worst thing about the experience was that no one ever reached out to me to inform me of their decision on the position. I consider it common courtesy to inform an applicant, even if it's a standard automated email, whether the position was filled or not.
