What's the best way to interview someone?

Something that I learned early on while writing was to always have a small tape recorder with me at all times, so I could record thoughts, or if I had an opportunity to interview someone related to my story, I would have it with me to do so, with their permission of course. Most phones today have a recording feature so if you are able to interview someone for a story you’re working on and you have their permission to do so, you can also use that.
