It's a Q&A format. Probably done over email since there's not a lot of back-and-forth banter. The interviewer doesn't say "Oh that's interesting! Why'd you do that?" But that's not a knock, it looks good so far.
The interviews were done using a combination of email and Skype.
Gah. Sometimes I am so twentieth century. I keep forgetting such things can be done via Skype these days. (You can tell I'm not a Skype user, right?)
