Boomi Account Executive interview questions

I was reached out to by a recruiter via phone and didn’t initially have a follow up until I received an email stating they wanted an interview. I knew little to nothing about the job prior to my interview and had to find the job posting online to learn what it was about. Upon my interview, my interviewer was late but, it was a good conversation. I honestly left the experience feeling very excited about the opportunity and looking forward to moving on in the process. My interviewer stated that they wanted me to move on in the process and I’d be reached out to soon to schedule the next interview. I followed up via email to thank them for their time. I then received an automated email saying that I will not be moving on in the process. This frustrated me because I had no feedback on why I was not a fit like I was originally told by the recruiter and my interviewer.
