There were three interviews in total. I was fist introduced to the company at a conference and had an informal interview there. After, a couple of weeks I received an email for another interview on HireVue. HireVue was an app that required you to record yourself answering several prompts. The last step, in the process was a Skype call with two hiring managers. These interviews were more personal and they were trying to get to know who you were while also trying to get a feel for how much you knew. I got a response the next following week.
