SAF System interview questions

I was found by a recruiter and than contacted over a job. I found it quite interesting the position, and moved forward to a quick call with the recruiter. This conversation went fine, and I moved forward to talk with the CEO and the talk was a bit awkard if I might say. A few questions were made, but there wasnt much structure if I can put in that way. Also, in the site was basically no information about the company and product, and on Linkedin there were only a few profiles, and 3 different ones from the CEO which made me uncomfortable with the process.
