ASML Business Analyst interview questions

Applied online and then received a call from HR. I was invited for 2 rounds of interviews at the office HQ. Questions were about my experiences and how it related to the job role i applied to.

I got a call recruiting manager that my cv was shortlisted and I will be having a thirty minute call. The initial screening went well and after that I had a technical interview with two persons from ASML. The interview went extremely well and I explained about the work I have done. They behaved as if they were very impressed and at one point they have even mentioned where and whom I will be working with. After the interview I was told that they have a very positive feedback and I will be contacted by HR and I need to give an exam and after that I will be joining the team and the entire process takes three weeks. I was very happy and returned back. I haven't received call for two days and then I called recruiter and said about the interview. She came back saying that the interview was very good but we are not considering me for this position. I asked her where it went wrong as the interview went very well and even requested to talk with the interviewers . She declined saying that it's not possible. Still don't know where it went wrong..
