Some people are tempted to take notes, throughout the course of an interview, as a means of coping with the process. This may help with the nerves but unfortunately it creates a very negative impression. Furiously scribbling notes whilst someone is talking to you is very rude. At the same time you are not able to make that all-important eye contact with the person, so you are "disconnecting" with them. That only serves to make things worse.
It makes you come across as insecure and craving detail. These are two characteristics that are not easily accommodated in the workplace. You should know the answers that you gave to any given question, so why would want to write anything down about them? The greatest details that you should be interested in are the answers to questions that you will pose. An average memory should be able to remember those. If not, your ability to do the job without resorting to pen and paper will be called into question. So do yourself a favour and don't make written notes.
