Johnson Controls interview questions

Initial phone screen with HR just asking availablity as the hiring manager was interested in my resume and wanted to bring me in for an interview, and asked the salary range I was looking for. The in person interview, I met with the manager and director.

An average interview, but no reimbursement of travel expenses. I was approached via Linkedin for this role. After a telephone interview I was invited to have an interview in Bratislava. I live in Prague and traveled there for the interview, 650 kilometers/400 miles there and back. I was promised travel reimbursement. The interview was what I would normally expect. I was interviewed live by the Regional Finance Transformation Project Lead E/A, Regional Transition Lead and via video with the HR director BA. I did not get proper feedback (a 'no' would have been enough), but worse my travel expenses were not reimbursed, despite several reminders from my side. I took a day off and traveled there and back just for this interview. I have been in contact with all people involved in the recruitment processes, and sent them several reminders. Despite responses that there would be a follow up, nothing has happened until now.
