Applied through internal recommendation via current employee that I know. ~2 months later, had the phone interview and it went well. Mostly technical questions related to position and questions about my background. 1 week later, I was invited to come on-site, where I had a full day (8 - 4:30) interview. Met with pretty much everyone in the group (17 people, either 1 on 1 interviews or 2 on 1 interviews) for 30-45 min each. Was pretty tired by the end of it but thought it went well. 4 weeks later I was told that they decided to make an offer to someone else, but I was in the top 3 candidates considered. Asked for specific feedback, and waiting on that now.

Got interview in the early November. 30 minutes phone interview.

I applied through email listed on the site. I was contacted directly by manager within 2 weeks for a phone screen. Initial phone interview was very quick 20 minutes. Mostly background explanation and some questions about previous work. I think depending on where you get call from knowing in and out of the field whether you worked in there or not will help.
