In a few rare cases a prospective employer may request that you create a full presentation as a requirement of an interview. You may find this situation a bit awkward, especially as you're nearing the end of the presentation — a poor ending could cause you fall out of the runnings. Take the time to craft an interview ending that will leave a positive impression on the employer.
Create a final presentation slide that summarizes all of the main points you made in your interview presentation. For instance, summarize what you've presented about your experience, major projects you've completed in the past or industry-related concerns that you feel you can help the company address. Leave this final slide screen up on the screen as you close.
Verbalize the summary slide and provide a "clincher" statement to end the interview. A clincher statement is a brand new detail that adds to the already compelling story you've presented to the hiring manager in order to close the deal. For instance, if you've discussed your past experience as a photographer to the hiring manager, a clincher might be that you won a major industry award for your photography work or photographed a number of celebrities.
End the presentation by expressing the two or three main reasons why you want to work for this employer in particular. Do your research and identify specific news stories or characteristics of the company that you find particularly interesting to your career goals. It is wise to customize your presentation for that specific employer rather than using a cookie-cutter speech.
Encourage the hiring manager to ask you questions about the presentation if he needs clarification. A question and answer session is usually a smart way to end the presentation because it can create a fluid dialogue between you and the hiring manager instead of continuing a one-way conversation.
If you have a portfolio of images, which is common for certain types of jobs like graphic design and photography, display some of those images behind you instead as you conduct the question and answer session.
