I am going for the phase 2 of my interview and was given 5 subjects to choose from. They did not say that I had to use visual aides. Should I call and ask if they expect that or is it common knowledge? This is my first ever presentation.

If you can use visual slides. Research shows that a visual presentation is twice as likely to achieve your objectives. It is usually always a good idea to find out as much information about what they expect and also a little bit about the layout of the room that you will be presenting in.

It will also be worth making sure that you have a print out of your slides. This way if the projector for whatever reason does not work you will still be able to use your slides.

Good luck
