Applied online on the website, was contacted by HR. Had initial phone interview with HR, followed up by phone interview by hiring manager. Was then invited to come onsite for an interview, and interviewed with 4 people (progam management staff & engineering staff) over 3-4 hours. All interviews were 1-1. Everyone was extremely friendly. I also felt they were pretty straightforward about some organizational and process challenges that they were facing. No major surprises in the interview, typical questions were short & long term career goals, and how did I handle unforseen issues that came up in my previous projects.
