Maven Systems interview questions

I applied to Maven interview. The office was very difficult to find. It's almost an apartment and office is in first floor. The interview was really bizarre and dull. I kind of performed very well in interview, but I wasn't selected though. The scenario of interview completely changed after I told I had experience. They are only recruiting freshers, I guess. They sent a mail after that I don't match their skill set. Disappointed a bit!!!

It was difficult to know about openings in first place. but now I have seen company is posting their requirements on job portals. Hiring process was mainly carried out through face to face interview. The interview was mainly technical based on embedded c programming. interviewer also asked some background question.
