Indigo Account Manager interview questions

First round was a video interview where I was timed on my answers. After thay I was notified they wanted to interview me in person. They flew me to one of their main interviewing locations where I spent the night and spent the entire next day interviewing. All they did was tell me how impressive my credentials were and how well I interviewed. I had to present their company in a presentation and meet with several panels of people. After the interview they told me they would let me know if I got the job or not in a couple of days... I never heard back from them. I followed up with no response. By far worst interview I have ever gone through as I went through all of that only to get no feedback.
