Focus accomplishments on the job opening whenever possible. Answer with results produced rather than duties given. Respond with strengths that correspond with qualities the employer is looking for. Take a weakness from long ago and explain how you overcame it. Don't shoot yourself in the foot by bearing your soul to the interviewer.
Input is encouraged when it helps lead to efficient mission accomplishment.
Input must be presented in a professional manner. Never criticize a superior in open forum. It is possible to disagree without being disagreeable. Always do research about the company ahead of time to have a general idea about their bottom line. Make a list of specific skills you have acquired in previous jobs that qualify you for the current opening.
