Straight To The Point Answers:
Try Not To Inflate Ones Role:
Inflating one's role and impact on the organization is a sure shot recipe for disaster. Also it is good practice to own up or acknowledge past mistakes on the job and showcase them as key takeaways for the future.
Try To Have A Corporate Approach:
The first thing to be looked at is your dressing. In most cases try to wear a blazer. Your attire demonstrates your seriousness for the process and respect for the interviewer.At times, candidates stroll into an interview without prior research on the company and the industry, this is totally not good.
Volunteering excessive information and showing undue familiarity with the interviewer / hiring manager is a big put- off. It is always better to maintain a veil of formality in your interactions with various stakeholders during the interview.
Poor listening skills
Most interviews are about good listening skills. It gives you a chance to understand the role and the company and also not to over-expose yourself during the early stages of interview.
Try so well not to make negative remarks about your former employer. Even if the concerned individuals or companies have a bad reputation, maintaining a neutral stance is better.
Showing undue haste and anxiety in bagging the position is a clear sign of weakness and hampers your ability to negotiate a good deal. Maintaining a positive and healthy ego right through the interaction will help in positioning your candidature for the job in a much better fashion.
Excessive focus on compensation
This is a serious put off for most companies. Some candidates focus on the minutiae while missing the larger picture. Also candidates come up with unrealistic expectations citing personal compulsions.
Let's remember that to be a successful CEO is one thing and to become a CEO in the first place is another. But common sense dictates that the very qualities which help you become a CEO should give you a more than reasonable chance to make a success out of that job. Good luck!
