Can i judge person if he is not wearing shoes on interview?

P.S. And where is his tattoo?

P.S.2: he is talking about N900 and idea of making it opensource. He is using opensource as always in any opportunity

P.S.3: i want to point out that I do not like that people saying "I used to.." "I was ..." but at the end we see the results that there is no more maemo, meego or Jolla. It sounds like "I can move mountains with my thoughts, I just don't want to" =)
