How do you prepare your interview presentation?

It is not strange when recruiting for the senior roles, or where presentation is going to play a role in the job, to request interviewees to do presentation as part of the interview. This is a good opportunity to prove your potential employer what you can achieve, outside the formal interview questions and answers process.
The most essential thing is to identify who you are going to be talking to. This will certainly influence how you deliver your presentation. Find out the number of interviewers who will be on the panel and their skills on the subject as this will assist you in your presentation.
You should have a clear message that runs through your entire presentation, and always limit yourself to these three sections: The Introduction, development of your argument, and then the summary.
Make sure your ideas are understandable and appear in a logical sequence, using sentences that are short and snappy. When calculating how many minutes to give to each section, allocate 10-15 percent for your introduction, the same for the conclusion, and the rest for your main content.
Keep your introduction effective and give a memorable conclusion that will have the audience satisfied with your presentation. Speak clearly, slowly and with a purpose; avoid any rambling. Make frequent eye contact with your audience.
Try to commit your presentation to memory. It will rescue you having to grope around with PowerPoint slide or prompt cards and will give a good impression of your professionalism and confidence. However you want to present, practice your presentation ahead of time, testing it on relatives or friends.
If you are using slides, maximum content is supposed to be headline and maybe 3 or 4 bullets per slide with diagrams and graphs where appropriate.
Keep away from glancing down at your screen for prompts – if you have memorized your presentation well, you will not even need them – and speak to your audience, not the laptop.
Answering questions from the audience gives you the chance to further show your knowledge of the subject. Make your audience know earlier that you will be taking their questions towards the end so they do not interrupt the flow of your presentation.
Deal with the questions you’ve been asked, not the ones you fancy answering. Repeat every question as you get it and give yourself a minute to think about what is really being asked.
