I had an initial phone interview which lasted about half hour. The person from HR who contacted me asked mostly about my previous work experience, and why I wanted to work for AB. A few days later, I was contacted to come in to their offices. I had two interviews. All behavioral questions, no technical.

Very long, 8 interviews in total. Each interview lasted approximately 30 minutes and each interview felt almost identical. Just bounced around between department heads. In total these 8 interviews were spread out over about 6 weeks.
