how to prepare for a interview

[Julien]

Is it better to make a presentation during the interview, like power point? Does it seem too rigid? Moreover, in many cases, we mostly need answer questions, not show ourselves, so, we probably have no time to say something in the presentation.

Is anyone asking you to make a presentation? Unless they are, you just show up and have a conversation with your interviewer(s). They will ask some questions (you can search the Interviews subforum for common ones), you'll answer them, you'll ask them some questions back, and that's about it.
