3 rounds Optum Dublin, Ireland HR screening (try to know you, checks alignment, salary expectations) Technical round with Team (Principal Data Scientist and Senior Data Scietist) Final round with Director and Senior Director. (the part where you have to sell your soul and lie every step)

Had 2 rounds of interviews and both of them went really well, lovely interviewers as well. After the 2nd round I was told that the interviewers were really impressed, recruiter asked me about my relocation process which all went pretty well and he said 'unofficially' it was all good and to expect the offer in a few days in the same week.. until I told him that I was going on a short trip the next day - which should have no effect on the process because I completed everything and was leaving the next day - but the recruiter got annoyed, asked me where I am going and asked all sorts of question around my trip and the whole attitude changed. It should not have any affect on the selection process (right?) as my notice period was only 2-4 weeks anyway. He called me the next day and said the interviewers have selected someone internally and I was out of the process. It was all so bizarre. Steer clear of any of your travels/plans/your home country because they can use that against you for reasons unknown.
