They use a third party tool called HireVue to conduct the interview. You don't actually talk to a human and cannot engage in conversation. You're basically just talking to yourself into a computer, making a timed recording, answering questions that they have selected to ask you. It's a one-way communication with no back-and-forth. I'm used to actual conversations with real people so it just felt strange. I wasn't surprised that there was no offer as I definitely don't do well in such a situation. If you like to engage with people, this interview process is probably not for you. In the future, I definitely know to reject interview offers from companies that use this method. Live and learn.
