Adobe Manager interview questions

Applied online via Adobe website. Had conversation with their recruiter, then 30 mins with hiring manager and two further 60 min calls, each with 2 business stakeholders. These three stages happened very quickly and seemed to go well, but since then several weeks have gone by with no feedback on whether I made it to the final stage (which was to be panel interview & presentation). Polite email to the recruiter to enquire on application status / timescales went unanswered. I assume I didn't get the job, but think after the time invested, it would've been a courtesy to update the unsuccessful candidates. Very unprofessional.
