Kepler Group Digital Analyst interview questions

HR reached out to me about a month after applied on LinkedIn and then a week later had a conversation with the director of analytics. Then a couple days later, they contacted me for the final interview with four members in the analytics team where I would have to present a presentation. This interview process was very unprofessional, I had prepped for the interview questions and created my presentation which took about 1 to 2 days and literally 30 minutes before our Skype interview, HR emailed me telling me the position was filed the day before. They could have at least interviewed me and let me present my presentation and then decide on their final candidate but they did not even give me the opportunity to present my presentation and do the final interview before hiring someone for this position.
