Well. It happened a year ago. I applied for this position in Brno, Czechia. After about a month I got a call from hr and they wanted interview with me on the same day. Come on! I need to prepare and arrange it in advance first. The interview finally was ok. Second round I had discussion with the manager. He gave me offer and promised me an official offer letter. Well. This is that I never ever received. They simply ghosted. Finally after many months I received a refusal email.
