Qatar Airways Customer Service CSR interview questions

I was originally scheduled for a final interview in-person for a remote position. Originally, Qatar was not willing to reimburse my travel expenses, but I agreed to the in-person interview anyway and secured transportation. 5 days before the interview my time slot was abruptly changed. 3 days before the interview, my time slot changed again and I was informed that the interview would be virtual and the following morning. I had to pay cancellation fees on my train fare that were not reimbursed. I agreed to the rescheduled time and format, but was feeling a little uneasy. The interview was not that great and I felt as though the responsibilities and candidate requirements shifted with each interview I attended. I was also never told the salary band for this role, only that there was no bonus structure. Although it seems like a respected company to work for, the interview process itself was unprofessional and left a bad taste in my mouth.
