DeepCode interview questions

The process was that there was not a process. I learnt about the company online and I liked the idea. After that, I checked out for job vacancies and there were none; only in a small corner in the website stating that if you're interested in the company you could write an email. So I did. After a week or so, I got an email in order to arrange an interview. At the (google hangouts) interview, I am immediately asked technical questions. The interviewer never introduced himself nor the company to me, nor the position I was applying. Then he tried to do the "google" interview with me and asked me to solve some algorithmic problem in google docs. After I solved it, it was very very awkward, did not state when I will have results, just said thank you and hung up. It was the most unprofessional experience I have ever witnessed. Massive RED FLAG. And of course, I did not receive an email of any kind after this.
