Contacted by a recruiter whom I had never spoken over the phone. He setup a phone call with their tech lead, a very nice guy. After that, they set up an on-site. Typical coding and general questions about your background. The CTO is a very knowledgable person who used to work at the Hololens. I guess he mistaken me with another candidate who is supposed to have in-deep knowledge on video encoder&decoder. Anyway, I enjoy the experience and learned something new from the CTO. No matter what the outcome is. I wish you all the best!!!
