Urban Sky interview questions

So far I just had a phone interview with the CTO. He was a half hour late, emailed to reschedule, then called out of the blue fifteen minutes later to have a "quick tag-up." He described the job, and patiently answered my questions. I then had to give a brief overview of my background, after which he said he needed to go to another meeting but he would email me to chat some more. I have yet to receive another email from him.
