The process at ActiveCampaign was one of the best I've experienced. The overall process from application to offer took about 6 weeks. The process included a phone screen with the internal recruiter, four 30-minute video interviews and a short written exercise.
The internal recruiter was incredibly communicative and helpful and I never felt like I was being jerked around or like my time was wasted. They were very upfront about salary expectations and the offer negotiation process went smoothly.
