When I applied I had emailed the hiring manager too. I applied around November, and heard back from hiring manager in January. It went well. Recruiter called me 2 weeks after that. And I immediately had to fill out the candidate questionare after that. A week later, someone contacted me to plan the on site interviews. It was actually 4 weeks from then because of other scientist's availability. Onsite interview started with my research seminar. They asked a lot of questions, some a little difficult. But they were all very intelligent questions. Executive director and director of the department was present for the meeting. Then I had one on one meeting with senior scientists, principal scientists and the directors. Lunch with lab members and back to more one on one meetings. I enjoyed talking to them. They asked about some behavioral questions but mostly about my experiences and future plans. What are the skills I want to develop etc. at the end of the interview, the hiring manager asked me to send recommendations. And my advisor got a request a week later. And another week until I was selected (mostly because I followed up a lot because I received a competing offer).

The process is more rigorous and scientific rigor is appreciated. You will have a phone interview followed by on-site interview for a day or two. You will give technical seminar followed by one-on-one interviews.
