Two phone calls, followed by a video chat with someone on the team and a final round with group of 4-5 SEs at Attentive. Final round was a 50 minute presentation that you had to give. Second phone call, HM said the company is "slow to hire but quick to fire" word for word. Recruiter would call me every time I did not have an email response for scheduling within five hours. Very pushy, generally very negative experience.
