The process took 1 day. I interviewed at GE (Schenectady, NY) in Jun 2012
Interview
A recruiter contacted me about the position since I am currently employed and not looking. He did a short screening with me and then I had to "apply" online. After that he sent me questions via email and had me answer them and then another phone interview with him. My answers to both the email questions and the phone screening were then sent to the hiring manager.
A couple of days later the recruiter called me back to say that the hiring manager wanted to have phone interview with me. Phone inteview with hiring manager was 30 minutes and he invited me on site for an interview.
The onsite interview was a full day of interviews starting at 11am and going past 5pm. Each hour was with a different person and one interview was during lunch (eat, talk, answer questions). Everyone was very nice, engaging, bright and focused. I personally had a great time meeting with everyone and discussing the vision and direction of the business.
No questions were out of the ordinary, the typical what are your strengths, weaknesses, greatest accomplishment, how would your supervisor describe you, are you techincal enough for the position and how so, etc. In the first interview he had me grab the dry erase pen and go up to the white board and in 8 minutes teach him about something.

Interview
A technical and a HR interview. Both are easy provided you know about what you have done. They take students with masters and PH. D. degree, so having a through knowledge of your thesis work or paper published helps a lot. They also conduct a written test for shortlisting of candidates.
