BR+A interview questions

No recruiter screening, I was scheduled an interview directly with 3 director level engineers. The 1st round interview went well and they wanted me to come into the office for a 2nd round on-site interview. After the recruiter scheduled the on-site visit, she ghosted all my emails with questions regarding travel which I thought was weird. A couple days before the interview, she cancelled the interview last minute and told me the position is filled. Although the interviewers were nice, the HR department was very unprofessional and left a bad impression.

Asked Resume questions, knowledge about the company and what was my favorite course. Also talked about the company and projects. Very laid back easy interview and talked about the position.
