Had an initial call with HR rep. After that I had a phone interview with a manager and another engineer. Finally, I came onsite for a full day of interviews. During that day, I interviewed with 2-3 people at a time for an hour or so. Then they would leave and new 2-3 would come in. You don't have to worry about behavioral type questions. Most of them want to know about your background and how you feel about forensics work. Some of them just liked talking about themselves.
