Interview
Three rounds of interviews--first a 30 minute phone screen with the hiring manager, then a 1.5 hour in-person with the hiring manager, and finally a 3 hour interview with the hiring manager and two other team members (three separate interviews). From application to offer it took about 2 months.

Interview
Contacted by HR for phone interview. Basic resume questions and then invited to on site interview. Met with four people separately for about half hour each. No communication after the onsite interview. Not sure if the position was filled.
Online application including Statement of Objectives, CV, 3 Letters of Recommendation, and short response questions about fairly basic things like research interests and summary of awards/recognition. Notified via email unofficially of acceptance on February 9th. No interview, however some applicants did require an interview. Seems to be a case by case basis for interviews.
