Mastodon Design interview questions

I met 3 of the software devs that make up 2 different teams at a coffee shop and we chatted about my resume and the few things they could actually tell me about the company. It was a very comfortable experience and by far the best interview I have had to date.

A quick in person meeting where they asked me about my experience and decided where I might be a good fit. They invited me to their headquarters in Rochester, NY where I spent about 30 minutes talking to their head hiring guy. He printed me resume and asked various questions pertaining to my knowledge of various skills I had listed as well as questions about Embedded systems design.
