Bailey Abbott interview questions

I was contacted by Bailey Abbott’s HR team to arrange a phone interview. They sent me an email with a calendar link so I could select a time from the available slots, which I did. The following day, I received another email advising that there was a scheduling conflict and asking whether the interview could be moved to two hours later than the time I had selected. I replied and confirmed that I had no issue with the rescheduled time. On the day of the interview, I waited for the call, but no one contacted me. I assumed there may have been an unexpected issue on their end, so I followed up by email and asked whether the interview could be rescheduled if the role was still open. A few days have now passed, and I have not received any response. Overall, I found the experience disappointing and unprofessional. I understand that scheduling issues can happen, but a simple follow-up or apology would have been appreciated. Unfortunately, this left me with a negative impression of the recruitment process.
