No matter how expert or experienced you are, when you are applying for a promotion in your own organisation, or a post in another organisation, being fully prepared for the interview is critical. Your expertise, knowledge, reputation, experience, and appearance, will help you, but it is highly likely that the other candidates will have similar attributes.
Here is list of actions that you should carry out in order to be fully prepared. Gather information about the recruiting organisation (this includes your present employer if it is an internal interview): before you decide whether to attend the interview, it is essential that you gather information about the organisation and analyse this. You need information on its recent and forecast performance, the condition of the business sector in which it operates, and the post that it is offering. If the organisation and sector are healthy, and the post looks secure and has potential, then you can move on to the next stage. If your findings are negative then it is almost certain that the best decision would be to reject the opportunity. You need to gather information about the condition of yourself, looking at how your personal and career plans are progressing, focusing on how the prospects in your current job match with your personal and career objectives, and then how the new post could help you to achieve those objectives.
Decide to attend or not to attend the interview. You need to make an objective decision as to whether taking up this new post is the right decision for you, at this time. Armed with the information that you gathered earlier, you can assess the merits of being appointed to the new post, against staying in your current post, albeit perhaps until a more appropriate opportunity arises, and make your decision confidently. It is, of course, tempting to apply for a job which appears to offer a higher salary, more responsibility, more status, and new directions, and if this is so appealing that you are confident that you can adjust your development plans to match it, and be happy with that decision, then yes, attend the interview and perform to the best of your ability. However, be warned that the interviewers may well reject you because it will become obvious to them that the position they are offering is not a natural fit with your career to date, and worse, they may well ask you how this new opportunity fits with your future personal development plans, and be disappointed with your unconvincing response.
