Wow! Sounds completely the opposite of my Interview.
Tech Guys were great, made you feel relaxed, not too many type specific questions. HR lady was OK But as with All HR types, I guess you should take the Bull by the Horns, this will enable you to "Control" the Interview. Be Proactive.
I did not seem to have any problems with the roads around Katowice???? No Sim Check either.
