7.  Do not talk too much!

Always remember that communication is two-way things so give them a chance. Also don't interrupt to interviewer when he/she is talking. Give him/her full chance to talk.

One common mistake candidates make when interviewing is talking too much. It is important to listen to the question asked and answer that question. Keep your answers to two to three minutes at the most. When you limit your time, you tend to stay more focused. It is very easy to stray off the subject and ramble about things irrelevant to the job if your answer is too long.
