Saying you want to be CEO or head of department during an interview can automatically pigeon hole you in a hiring manager's mind, so avoid this by steering well clear of talking about specific job titles.

To do this, focus on job responsibilities that you would enjoy carrying out, skills you would like to develop and passions you would enjoy making the most of in day-to-day working life. This will show that you have really thought about the role in hand, your future and how you can apply your existing skills to the company.
