Edwards Application Engineer interview questions

I was approached by an external recruiter and they help setting up 1st interview. I was interviewed by the hiring manager and her boss. Experiences and examples of achievements were asked. In the end, the hiring manager asked me to do analytical troubleshooting on excel raw files to see my thought process. Both interviewers were quite nice. I was then invited to 2nd interview to present a case study. There were 3 interviewers this time. I had to say I did not expect the 3rd interviewer since I was not informed beforehand and he asked multiple questions that were already asked in the 1st round of interview. That was such a waste of time that I had to repeat myself. This is a negative experience for me. One thing that strikes me though, is all of them asked about my marital status (It felt as if it were that important in the hiring decision).
