Initially there was a phone call where I was accepted for the in person interview process- which occurred at the Carnegie Science center after a week or so I had scheduled an in person interview with the director of the section i had applied to and a second person tagged along in the interviewing process asking minimal questions compared to the main interviewer. It was fairly easy but about 5 questions were quite elaborate and not the norm for interviews I have experienced in the past.

Very straightforward. I had a phone screening confirming pay and interest and was then called in for an interview. I was given an offer approximately 10 days after my in-person interview.
