There were 5 interviews about 45 mins each. They generally asked about the same questions, all behavioral. If you just say you want to work for GE for the rest of your life you are likely to do well. Just make sure that when you answer a question in one interview you remember your answer, a similar question might come up later and you have to answer them about the same so that when the interviewers compare your responses they know you were telling the truth.
