If there were problems with previous experiences, try to put your answers in the positive rather than the negative. If you slight a former employer, the interviewer may assume that you will someday do the same to him or her. Try to Be as Specific as Possible. Take charge of your own life or someone else will take charge of it for you. Watch Your Grammar.
Employers are interested in candidates who can express themselves properly.
Prepare to Ask Questions. When asked for comments or questions, have some ready, this shows that you are prepared and interested. Even a preliminary telephone interview can help you assess whether or not it would be worth your time and expense to travel for a personal interview. Be Careful With the Closing. If you are not good at closing conversations, don't linger.
