Euromonitor interview questions

Was contacted for a phone interview about one week after submitting an application online. The first scheduled phone interview came and went with no call. The HR rep claimed something came up, though I received no email (red flag). The second phone interview was later than we scheduled, but I was called and it lasted approximately 15 minutes. It was mostly focused on getting to know me and a description of the position. Standard questions here. Was contacted the next day to schedule an interview via Skype with a department head. Skype was abandoned and the phone was conducted via telephone. This interview lasted roughly 50 minutes. The questions first focused on my history and then moved to more hypothetical case-specific questions. This interview was followed by a written Excel test. The Excel test was sent to me via email and I was told to complete it at my convenience, though within the stated timeframe (1hr30min). Following the Excel test, I heard nothing for 3 weeks. During that time I sent a few follow-up emails, though I received no response. I eventually called though I was unable to reach anyone. I was then contacted via email saying they decided to go another direction. Ultimately, the process left a lot to be desired from their end.
