The process took 2 days. I interviewed at IBM (Hawthorne, NY) in Aug 2007
Interview
I was first contacted by e-mail by a hiring manager. He indicated he found my profile online. He invited me for an on-site interview. The interview consisted in a formal presentation with slides, in front of about 20 people, followed by a one-on one interviews with about 12 people, over two days. Some of these people were managers, the others, technical people. They wanted to know about my accomplishments, what was the most challenging part, how well I collaborate with people, and how much initiative I showed in the past.
I applied through an employee referral. The process took 4 months. I interviewed at IBM
Interview
I gave a scientific talk on my research, had a roundtable discussion, went to lunch, and had 6+ one-on-one interviews. Overall a pretty laid back process. Challenging, but intellectually stimulating questions.
I applied online for the researcher position and had the first interview. Asked about background information and why choose IBM. They also asked which area you would like to specialize in the future and why. Questions were very straightforward and nothing to stress about. Overall a quick and easy experience.

Interview
I went to the place for an interview day and to give a seminar. The interviews where ok, without much technical questions. Then I had phone interviews with the managements for few weeks, again a bit going through the CV. They didn't give me feedback at the end of the process.
