Call with the hiring manager followed by a call with a GE recruiter. The final round was a day of interviews with the hiring manager, HR, and three other people.

I applied, and got a phone interview with HR a week later. I couldn't schedule a time, but instead was given a time to interview. Almost exactly a month later, I got a phone call from the hiring manager going over my resume and discussing job duties. That same day, I was offered an onsite interview, which occurred a week later. The onsite involved meeting with 4 members of the engineering team, and was very casual and behavioral. The last meeting was with the hiring manager, and we went over a problem on a whiteboard so they could observe how I think. I am waiting to hear if I got the job or not.

Received a call from the team leader and we spoke for about 20 minutes about my resume and the position. Two weeks later they flew me out to meet 4 team members plus HR. Interviews were informal and mostly consisted of going over the experiences listed on my resume and common interview questions (weaknesses, strengths, etc.)
