Expedia Group interview questions

I applied online, was emailed the next day and offered a chat with HR and an interview was scheduled in. On the day of the interview, 10mins prior to the start time I received an email that a (BU Sync) meeting was going to be running over for at least an hour and could I please suggest an alternative time. I suggested other dates and times however I never heard back from them, despite following up a few times. Completely ghosted. I was surprised this experience with Expedia and I found it disrespectful and unprofessional.
