I attended OD in Prague. There was around 100 people. Two ladies from Malaysia were recruiters. We were waiting in a huge concerence room. We started with submit CV ('just leave it here') and English & math test. Some people got rejected after that. Then we had reach test & a quick conversation, we had to choose one piece of paper with a word on that and say smth about it. I had 'SMALL'. Yes, SMALL :D I told them that we all should appreciate the small things which happen every day bla bla bla. Then they asked about tattoos & moles etc I told them about my tattoo on my back, and I was super-smiled while saying that (as everyone advises), but it didn't help. After that like 10 people got in to the next stage. Obviously, I have no idea if it was about tattoo or not, but I think I could at least mention that I'm about to remove it? One girl who work for Qatar adviced NOT tell them, and in case I get hired, then remove it before going to Doha 0_o. There was a few people even from Phillipines who came especially for the OD! Also a few people who are trying every week (following Open Days) !! I thought that you must wait for re-apply, but obviously no :) Anyway, I'm happy I went there, as I realized it is NOT THAT SCARY, but.. ehh how to say.. it's all about if the recruiters like you or not ;) What suprised me: there was many people who actually have no idea about QA, just wanted to see what's the OD :O To sum it all up: go there, be yourself, it's not up to you anyway :D
