1. Don’t make false claims about your past job performance. False claims about work performance can easily be verified. This is especially important if you are trying to stretch the truth or clearly fabricating information. Recruiters and hiring managers are spending a lot of money to verify prior job information included in resumes and on job applications.
5. Don't schedule your interview at a time when your energy level is low. Sometimes you have no choice about the time you schedule a job interview, but many times you do. Some people are not "morning people" and early interviews are a killer. Fatigue shows not only in the glazed over look on your face, slow rambling speech and even in the way you sit in the seat. To keep your energy level up, make sure you are well rested and have eaten.
2. Don’t use cliché terms that everyone is tired of hearing. Everyone understands that there are industry buzz words that come with every job. Using them will give your interviewers an indication of how well you understand the issues and could be an indicator of how well you will do on the job. However, imagine you were the interviewer and had to listen to a number of job candidates back to back and they all said exactly the same thing in exactly the same way. After a while, you, like the interviewer might tune out as well.
3. Don’t speak badly of your current employer or try to distance yourself from your present affiliations. The interview is not the place to talk about how right you have been when everyone else on your team was bad.
4. Don’t get angry in the stress interview. You really do not want recruiters, hiring managers, or your competitors for that matter, to really see you sweat. Interviewers are looking for rational behavior to have confidence in your ability to execute well on the job in the future.
6. Don't be arrogant. Interviewers and hiring managers are not keen on hiring arrogant team members. Of course there is a fine line sometimes between confidence, which you do want to show and arrogance.
