Once i get visa, bought ticket to fly from Kutaisi (Georgia) to Prague (Czechia) in 25th of January. Staying one night in Prague and tomorrow i came to Brno. And new life began. 3rd of February was New Comers Day which all new employees who begin this day attended this event. Event took about 4 hours where beautiful girls from HR team give us information about company process. In the end team leader of our team took us to our workplace with our new laptops. While writing this post it's my 5th day. Everything goes as expected....
