I was contacted a week after applying and asked to complete a video interview by the next morning. Their system gives you a practice session, then has you record three video responses to written questions that are displayed on screen. I was told successful candidates would then get a phone interview. A week later I learned HubSpot didn't want to move forward. The process seemed a bit too rushed and superficial for them to reasonably lose interest that early on, but that's what happened. At least they followed up.
