Amphenol PCD interview questions

I had one interview via Zoom then they wanted to fly me out to their office for in person interviews. I had 4-5 in person interviews at their office outside of Boston, MA. They mostly explained the role and what they were looking for. And also how my prior experience would fit into the position. They provided hotel & airfare for the trip to their office. I was told I would be paid back for any meals + transportation. It has been 2+ months & they still have not refunded me. In addition, it took them over a week longer than they told me to get back to me after the interview. They have been incredibly unresponsive & unprofessional post interview. This is what I was told in my denial email as well. " [Manager] has decided to continue with interviewing other candidates. He won’t be able to get back to you with a definite decision for approximately 2 weeks, as he will be out of the office all next week. We are sorry that we don’t have an answer for you right now and understand if you choose to pursue other opportunities." I also contact manager several weeks later as a follow up and was ghosted.
