HubSpot Editor, Content interview questions

Received a request via e-mail for a phone screening about a week after applying. Spoke with a very nice recruiter, who acted as a liaison throughout a process extending three rounds. Pretty generic first round. Spoke with dept VP over the phone in the second round, and on-site including two potential coworkers in the third. Interviews grew in rigor each time. Very close attention to industry knowledge; questions both regarding aspects of your background -- why you worked in certain areas -- and inbound marketing as a whole. HubSpot's competitors, what sets them apart, and ultimately what sets you apart.
