I love the idea, and kudos to you for creating this!
Some feedback:
1. Your enunciation sounds a little mushy, by which I mean your words seem to slightly blur together.
2. The questions don't seem to be connected. This is fine for a normal conversation, but in a podcast, it comes off as a bit disjointed. There's a lack of narrative to the whole thing. What's the purpose of the podcast? Is it to talk about food? About being a small food entrepreneur? What's the story here and why should I care?
3. When you talk at the beginning and end of the podcast (not during the interview), there's a certain false rhythm to the way you speak. It sounds like someone delivering a news report, which doesn't match the intimacy of audio or a podcast.
4. Music would be nice.
5. Some editing would be nice. It was nice to hear an unbroken interview, but in this case, I think it'd be better with some voice over explaining certain things so the interviewee doesn't have to. Maybe some background about the chocolate store. The state of the union re: chocolate. Something to break the monotony of just an interview.
6. Enthusiasm. This is sort of related to #3, but I don't get the feeling that you're excited about visiting this chocolatier (though I'm sure you are). Put some oomph into the voice and make me care like you do.
Sorry for listing only negative points; I really did like the podcast and learned some interesting things. Definitely has potential.
Looking forward to more!
disclaimer: I'm not an expert, I just listen to a lot of podcasts.
A student asking if a company is hiring full-time engineers is not naive in the slightest. You're writing purely from the perspective that all companies behave exactly like Twilio. In my experience (granted this was a couple of years ago), many companies at career fairs are sometimes looking only for interns. Some are just there for some advertisement, not hiring but still maintaining a relationship with the company.
With regards to the point about Java, rather than looking at just the language, I would think it's more worthwhile to see what a person has built with the tools they have knowledge of, rather than extrapolating that they are unwilling to learn something new.
What kind of analytics do you provide?
