Expedia Group Account Management interview questions

The initial phone interview with the HR manager was professional and they asked the usual questions. Every time I spoke or emailed the HR manager, he was deligent and replied timely. He did a great job from my point of view. I was told from the very beginning that there would be 3 rounds and no case study involved. Two days before the second round, I was notified that the hiring manager decided to include a case study. I did not mind however the assignment was clearly written last minute and was extremely vague. The second interview was a panel interview. They asked very basic questions that was hardly relevant to the job, especially a position that required at least two years of experience. There was an atmosphere of complete apathy and lack of enthusiasm. I asked if there would be a third round interview in which they said that they didn't know. Afterwards, I was notified that they will get back to me the week after. Surprise... surprise.. one month later and still no response. Overall, a very unprofessional look for Expedia. Communication and direction is definitely an area they need to look into.
